Flash-free GEvo Update
Mar 4th, 2020
After user testing (and some bugs reported and fixed), the new Flash-free GEvo has passed. It has now been made the default GEvo. Please let us know (email@example.com) if you run into any problems. Also, the old one is still available by adding '-old' after GEvo in links to GEvo.
- New: https://genomevolution.org/coge/GEvo.pl?fid1=2717714878;fid2=2344054529;dsid2=131558
- Old: https://genomevolution.org/coge/GEvo-old.pl?fid1=2717714878;fid2=2344054529;dsid2=131558
Flash-free GEvo Update
Feb 18th, 2020
There is a new version of GEvo available for testing: https://genomevolution.org/coge/GEvo-new.pl
This new version of GEvo doesn't use Flash (which is dead or almost dead). All old GEvo links will work with the new "test" version (just add '-new' after GEvo in the URL). If you have any problems, please email us: firstname.lastname@example.org
At some point in the future, the new GEvo will replace the old GEvo (and the old GEvo will be kept around as "GEvo-old.pl"
Sept 16th, 2019
Our attempt to add more hard drives to CoGe's storage array failed last Fri. For some reason, the storage unit failed to recognized three different types of HDDs we tried to add. We are not sure where the problem is, and will have to bring CoGe down again to figure this out. As usual, we will post downtimes through alerts on CoGe's home page.
50,000 Genomes in CoGe
Aug 1st, 2019
CoGe passes the 50k genome mark! The majority of these are added by individual researchers using CoGe's LoadGenome.

CoGe's Downtime explained
Nov. 2nd, 2018
On the evening of Oct. 29th, we were alerted by two researchers that CoGe was reporting failures loading new genomes. Thankfully, both of these researchers sent in the log report from CoGe. Analysis of them showed the same error:
DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::mysql::st execute failed: Duplicate entry ‘2147483647’ for key \‘PRIMARY\’ [for Statement "INSERT INTO feature ( chromosome, dataset_id, feature_type_id, start, stop, strand) VALUES ( ?, ?, ?, ?, ?, ? )" with ParamValues: 0=‘Contig16329’, 1=’129722’, 2=‘425’, 3=12001, 4=20906, 5=1] at /opt/apache2/coge/scripts/load_annotation.pl line 387
INT vs BIGINT
This was bad because the Duplicate entry ‘2147483647’ was the primary key in the feature table of CoGe. This key is autogenerated and should never get duplicated. We quickly realized that the number 2147483647 was special. It is the largest value for a 4-Byte signed number. A quick check of the database structure showed that the feature table's primary key was cast as INT (a 4-Byte number) and the source of the problem was discovered. CoGe had run out of numbers.
Fortunately, the fix for this is straightforward. Update the tables using this key from INT to BIGINT (https://dev.mysql.com/doc/refman/5.5/en/integer-types.html) and to an 8-Byte number. That would give a max number of 9,223,372,036,854,775,807. Which is a very, big number.
From that, we formulated a response plan:
- Put CoGe into maintenance mode
- Backup the database and all primary data (this runs weekly over the weekend, but we wanted to capture all the new changes). For those interested backups are made each week, stored remotely (CyVerse data store), and we keep weekly backups for four weeks and monthly backups for 4 months.
- Check to see if the partition housing the CoGe database would be large enough for the updated (nope!)
- Copy the database to a partition large enough to do the update (we used one of the storage partitions for experiment data that had 10TB of available space and was on SSDs for performance).
- Find all tables using the feature_id (there were 5 of them)
- Update those tables from INT to BIGINT for the feature_id
- Check the database for other tables hitting that limit and update those for good measure
- Double the tables to make sure nothing was missed
- After the database was updated, either move it back to the dedicated partition or, if the partition was too small, create a new partition and then move back
- Bring CoGe back up and test
Another item in the response plan was to make sure we posted regular updates to on the maintenance page as well as CoGe's twitter account. Nothing is worse than needing a research tool, having it down, and having no idea when it may be back up. While we weren't sure exactly when we'd get it back up, we wanted to make sure people knew we were working on it, checking regularly, and could be contacted for whatever reason.
Overall, the plan worked perfectly and CoGe was up and running again in about 4 days. The only hiccup was that access to CoGe and CoGe's servers is controlled through LDAP run by CyVerse. The night we put CoGe into maintenance mode, CyVerse's LDAP system crashed. While the CyVerse team was amazing it getting that recovered, it did stall our work for a morning (minus an hour of panic when we thought we had been locked out of CoGe for reasons unknown.)
How long will this take?
Unfortunately, the plan took a long time to complete. The reason for this is the shear size of CoGe's database. Even working on fast servers, SSDs, fast networks -- it takes a long time to move 2.2TB between servers. Table updates took between 12-40 hours each (they they were run in parallel). While the wait was excruciating at times, the main worry was that if any of these steps had an error, we would lose days of time. Fortunately, this didn't happen. Having a plan and a checklist was central to making sure that everything was done in the correct order, without having to restart. (e.g., if we messed up the database update, it would take a half day to pull a new copy of the database from the remote server, etc.)
The only error we made was not foreseeing that we were running out of numbers (filling the number space) for CoGe's feature table. Reviewing notes, this was identified as a future item two years ago (with the note that this would probably be a problem in two years). We didn't do the update at that time because we didn't have money to spend on SSDs for a large enough partition for the MySQl database. Well, we didn't want to spend that much money at that time knowing that in one-two years we could get twice the storage for half the cost (CoGe is a pretty lean project).
However, regardless of when we did the update, the downtime would have been the same. There is no way to do this kind of an update to the database without putting CoGe into maintenance mode. Every time a researcher uses CoGe, the database has changes made (tracking analyses, updating links, etc.) and best practices is to put the database in a state where no changes are happening before updating these tables.
But, we do want to apologize to all the researchers using CoGe. The one thing we could have done differently is to plan for this downtime, post an alert on CoGe giving a two week notice, and do our best to ensure that researchers could plan for this downtime as well. For that, we are very sorry.

GC% values added to API
July 20th 2017
when fetching a feature via the CoGe API, the percentage GC, AT, and NX values and the wobble percentage values are now included with the sequence and other feature info.
Multiple fastq support
May 9th 2017
Support for multiple fastq files when using BBDuk and BWA-MEM in LoadExp+ has been added.
Recommend Genomes for Certification
April 3rd 2017
To distinguish official genomes from copies or user-submitted data, we have added the "certified" indicator. Official genomes are manually assigned this status by members of the CoGe team. Certified genomes appear at the top of search results so they can easily be chosen when there are multiple genomes for a given species. When viewing a genome on the GenomeInfo page, users can now click a link to notify the CoGe team to recommend that they genome be certified.
NGS Analysis Performance Improvements
March 13th 2017
The NGS trimming and read-mapping pipelines in the LoadExperiment tool have been streamlined for a major performance boost. Compressed FASTQ input files (.gz, .bz2) are no longer automatically decompressed since most trimming and mapping programs support compressed inputs. Also, SAM-to-BAM conversion and BAM sorting steps are now performed on piped output from the mapping programs rather than creating intermediate files.
GATK HaplotypeCaller GVCF Now Available
March 13th 2017
BBDuk Trimmer Now Available
March 13th 2017
The LoadExperiment tool now offers the BBDuk trimmer as part of the NGS analysis pipelines.
Improved Search Results Interface
January 5th 2017
The "Google Drive" styled data browser featured in My Data is now also available for browsing search results. Search results, such as organisms, genomes, features, experiments, and notebooks, can be viewed, modified, shared, and sent to CoGe's analysis tools (SynMap, CoGeBlast, etc).
EPIC-CoGe Genome Browser Update
December 12th 2016
EPIC-CoGe, a genome browser built on top of JBrowse, has been updated with new data management, search and online analysis features. Users can manage CoGe experiments and notebooks from within the genome browser. Features of any type (gene, CDS, etc) can be searched for by name. Data tracks can be searched for max, min or a range of data values. SNP tracks be searched for particular types of SNPs. Tracks can be searched for data that overlaps features. Users can drag and drop tracks onto each to find overlapping data or non-overlapping data or to merge the tracks into a single track. A normalize transform has been added. Search result tracks can be converted to marker tracks and markers can be merged to remove gaps of adjustable length. Search results, transformed data and merged tracks can all be saved in CoGe as new experiments or exported to CyVerse via IRODS. Tracks can be filtered by name, metadata, tags, data type and whether or not they are private, public or shared. Support has been added for data beyond the [-1,1] range and tracks can be autoscaled on the fly. Online help has been added.
Advanced Search Features
December 12th 2016
Search results can now be filtered by various criteria available through a new GUI. Just click "advanced" next to the "Search database" input at the top of every page to access the new filters.

Normalization no longer required!
September 6th 2016
Normalization of quantitative experiment data is no longer required when loading new experiments. Previously, all quantitative experiment values were required to be between [0,1]. Normalization can still be optionally selected if desired.
August 13th 2016
A few years ago all of the genomes in CoGe were from NCBI, an official source. Since the addition of the LoadGenome tool users have added/copied 9000+ new genomes into the system. To distinguish official genomes from copies or user-submitted data, we have added the "certified" indicator. Official genomes are manually assigned this status by members of the CoGe team. Look for the Certified Genome icon at the end of the genome description.

Happy New Year
Jan. 1st 2014
2013 brought many improvements to CoGe:
- Advanced data management
- Loading your own genomes
- Integration of JBrowse
- Support for functional and diversity genomic data sets
- Lots of new genomes
Over the break, the CoGe team finally hunted down and fixed an outstanding issue with CoGe's database. We had noticed a long delay (upwards of an hour) during database inserts. At times, this would crash the database. The source of the problem was having a much too large query_cache for our database. While this would improve performance for many queries, each database insert required the query_cache to be flushed, which takes a long time when set to 256G. Lesson learned. Now, while our database performance is still quite good (4000+ queries per second), our database is again rock-solid during many inserts (e.g. loading genome annotations).
We are looking forward to 2014! As always, let us know if you have any ideas for CoGe.
-The CoGe Team: Matt, Evan, and Eric!
Major Maintenance Completed
Dec. 21st 2013
We just finished running a major maintenance on our database. We apologize if you experienced any problems or outages, particularly with LoadGenome, over the last few days! The work done should greatly improve CoGe's reliability and scalability in the future.

Happy new year! Development continues on the EPIC-CoGe Browser. An overview of the project and information on progress will be posted: here.
History of analyses and pages available to registered users
Nov. 5th, 2012
Improvements are continuing to CoGe's User System. If you are using a user account with CoGe , CoGe will record which pages and analyses you have run automatically. Some tools, such as SynMap, will automatically mark up those analyses in History with additional information (such as the genomes compared). If you want to revisit an analysis or page, but have lost track of it (or closed the browser tab containing it), you can retrieve it by clicking on "Data"->"History" from the menu bar in the top-right of any page.
Also, you can comment and mark specific analyses to save (and then find) for later.

CoGe "Data Tab"
Oct. 5th, 2012
With the roll-out of CoGe v5 comes the ability for users to more easily organize and share their data of interest. Most of these features are found in the "Data" tab in the CoGe menu located in the upper right part of the screen:
- User Profile: Shows what information CoGe's stores about you (user name, real name, email address) and a list of your groups
- User Groups: Groups of users to which you have access. These groups are used to share lists of data
- Data Lists: Lists of data (genomes, features, experiments) to which you have access. May be private or public data. It is through these lists and User Groups that allows you to share private data with collaborators
- History: CoGe has always generated tiny links for your analysis and views of data. These are now stored for you so you may more easily find a previously run analysis.
CoGe v5 Deployment Process
Sept 24th, 2012
- 9am: We shut down the website at 9am and started the final backup and freezing of existing data and analyses.
- 10am: Database is being replicated to the iPlant Data Store and copied to a backup server for processing and conversion to new database scheme.
- 11am: All web-code and libraries were backed up and new code deployed
- 12pm: updating database
- 1pm: copying database back to iRODS
- 2pm: copying database to coge server
- 3pm: reconfiguring the system
- 3:30pm: turn on web server
- 3:31pm: Nothing works
- 3:32pm: Start debugging
- 3:34pm: Get things working -- CoGe starts!
- 4:30pm: Most major problems found and corrected
CoGe v5 Deployment
Sept 21st, 2012
CoGe v5 is planned for deployment on Sept. 24th. This new version of CoGe represents a massive revamping and extension of the user-data management system.
Key features include:
- Limited support for experimental data
- This new system is funded (in part) by a grant from the Gordon and Betty Moore Foundation to add visualization support for epigenetics data for Arabidopsis. This is known as the EPIC-CoGe project: http://www.iplantcollaborative.org/learn/news/2012/05/24/iplant-ci-leveraged-development-epic-coge-browser
- Ability to make lists and collections of data
- Lists of experiments
- Lists of genomes
- Lists of features
- Lists of lists
- Enhancements for managing and sharing private data in CoGe
- Logging user history so it is easier to find old analyses
A key part to the migration to the new version of CoGe is preserving current private data in the system and assigning them to the appropriate owner. (We have done some major changes to the underlying metadata storage database for CoGe). Please let us know if you have lost access to your data and we will get that corrected right away.
New features will be added that further integrate user specified lists into various tools in CoGe. E.g. auto-selecting a list of genomes for use in CoGeBlast instead of manually searching for all the genomes.
Many thanks to CoGe Developer Matt Bomhoff for all the work on this new version.

Banana genome published
July 12th, 2012
The banana genome was published today in Nature: http://www.nature.com/nature/journal/vaop/ncurrent/full/nature11241.html
CoGe was used in some of the analyses (in supplementary figures), and the genome is now publicly available: http://genomevolution.org/coge/OrganismView.pl?oid=38351
Banana represents the first non-grass monocot genome to be sequenced and sheds light in the evolutionary history of the lineage as a whole.
My opinion is that the timing, placement, and make-up of the early monocot duplication events are still an open question. Some work points to an additional polyploidy event in the Poales lineage (See: Tang. et al. Angiosperm genome comparisons reveal early polyploidy in the monocot lineage. PNAS 2010; http://www.pnas.org/content/107/1/472.full). Banana, with its own series of independent series of whole genome duplications, is not the best suited for unravelling this earlier events, but these events open many avenues for additional research into the evolution and architecture of plant genomes. It will be exciting to see what similarities and differences exist between the monocots and the dicots.
Additional news pieces on banana:
Tomato genome published; the solanum hexaploidy investigated with CoGe
May 31st, 2012
The tomato genome was published in Nature earlier this week: http://www.nature.com/nature/journal/v485/n7400/
However, the current version of the tomato genome has been in CoGe for the past year (thanks to an early release of the data from the tomato genome consortium).
I've received a couple of emails inquiring about the Solanum specific hexaploidy, and this has been investigated with Haibao Tang. Overall, these analyses support that the majority of the genome is derived from a tetraploidy, but there is evidence of some regions being triplicated (perhaps through a hexaploidy).
These analyses are available: Tomato genome

2000 new genomes in CoGe
Apr. 30th 2012
The NCBI genome loader program was updated and run over the weekend. This resulting in about 2000 new genomes being loaded into CoGe.
Unscheduled CoGe downtime
Apr. 25th 2012
CoGe was down/offline yesterday for two reasons:
- One of iPlant's VMs was compromised and UITS (UA's IT group) shut off one of iPlant's subnets, which CoGe happens to use. This was due to a VM administered by a group collaborating with iPlant and not due to iPlant
- Since CoGe was offline, when it came up, we decided to keep it offline for a while longer in order to updated the apache web server. After apache was updated, CoGe was brought online. Unfortunately, UITS detected a security vulnerability in the SSL implementation in the new update and shut CoGe off. This last part happened at the end of the day and we weren't able to coordinate with UITS to push a fix until this morning.
While the CoGe team tries to keep as much uptime as possible, this type of downtime does happen once and a while. Our apologies to everyone whose work was interrupted or delayed due to this.
The algorithm, Last, added to SynMap
Mar. 28th 2012
Last (http://last.cbrc.jp/) has been added as a comparison algorithm in SynMap. Its performance is phenomenal! This is still under testing, so please let us know if you have any problems with it. Also, special thanks to Haibao Tang for writing the parallelized adapter for Last that is used by SynMap. Without this program, the integration would not have happened as quickly, easily, or smoothly.
CoGe used to decode the secret message in JCVI Synthetic Genome

iPlant User Management System Update
Dec. 18th 2011
The Data security model of CoGe has been updated. This includes creating CoGe Groups which permits the creation of user groups. These user groups may access a private set of genomes that is not accessible to other users of CoGe.
To use this, you will need to create an account with iPlant in order to be a registered CoGe user:
Major CoGe Update (version 4)
Dec. 4th 2011
Work is nearing completion for a new version of CoGe. While there are many minor improvements, additions, and changes to the tools, the major improvements are on the backend of the system including:
- New server hosted by iPlant: This means that the primary CoGe server will be located at the University of Arizona, Tucson
- Vastly expanded storage to hold even more genomes
- Enables the storage of metagenomes (as those datasets can be quite large)
- Modularized installation and centralized configuration: permits the rapid deployment of custom versions of CoGe (for those that may want a version of CoGe specific to their group of organisms)
- Federation with iPlant's authentication system:
- People will iPlant login credentials can log into CoGe as a registered user.
- Will enable the creation of personal data in CoGe
- Will enable more customization and saving of preferences for various tools in CoGe
- Will enable users to save particular analyses and datasets within CoGe
- Will enable import and export of data from CoGe to people's iPlant Data Store accounts
- Enhanced data security model:
- Will enable unpublished data to be restricted to a user or a group of users
Since the holidays are coming and usage of CoGe tends to decrease, hopefully any bugs won't affect too many people while they are fixed. The migration of the domain names registered to CoGe will change once the server has been reasonably tested. Other CoGe services will migrate after that (e.g. this wiki).

NCBI Genome Update: Over a thousand new genomes available in CoGe
Nov. 28th, 2011
The NCBI genome loading program for CoGe has been updated as is currently adding thousands of genomes from NCBI. Keeping CoGe current with all of the genomes at NCBI has been a challenge as their underlying data model for storing and organizing genomes evolves. The new program crawls all of NCBI's BioProjects searching for those with genomes and associated sequence. Prior to this data load there were approximately 12,100 genomes from 10,600 organisms. Approximately 40% of NCBI's BioProjects have been crawled and the current genome stats are:
Genomic Features: 99,814,749
For those that are curious, CoGe has maintained a MySQL DB transaction rate of 2000-3000 per second (majority writes/inserts) for the past 24 hours, thanks in no small part to its SSD configuration.
Note: After more performance monitoring, peak DB transactions top 9000 per second during heavy use from the genome loading programs and website activity.
Optical fun with CoGe
Nov. 22nd, 2011
Which direction does the DNA spin? Depending on how your mind is interpreting the dark and light colored dots of the DNA molecule as being "near" or "far", the helix can spin in both directions.
Thanks to Don McCarty for pointing this out.
Lamprey, Anole, and Frog genomes added/updated to CoGe
Nov. 19th, 2011
[www.ensembl.org Ensembl] version 64 genomes of Lamprey, Anole, and Frog have been added to CoGe:
Petromyzon marinus (lamprey): http://genomevolution.org/CoGe/OrganismView.pl?oid=30737 Xenopus (Silurana) tropicalis (western clawed frog): http://genomevolution.org/CoGe/OrganismView.pl?oid=33964 Anolis carolinensis (green anole): http://genomevolution.org/CoGe/OrganismView.pl?oid=33828
Thanks to Bill Spollen for requesting these genomes.
Updated and New Plant Genome Resources
Nov. 10th 2011
The CoGePedia Sequenced plant genomes page has been updated with the latest published genomes, including the just published genomes of both pot and pidgeon pea! In addition, we have added two new pages that may be of interest to those who (like me) are constantly having to pull together introduction sections and can't remember what the right citation for well known genomic information is:
- Plant Genome Papers lists the papers describing every published plant genome, when and where it was published, and how much attention (in the form of citations) the various genomes have attracted so far.
- Plant paleopolyploidy is a list of known ancient whole genome duplications among the various plant species with sequenced genomes including information on when and how the whole genome duplications were discovered.
Both pages are clearly works in progress so please continue to contact us if we've missed genomes, whole genome duplications, or citations which should be on the list.
Main CoGe Database is down
Nov. 3rd 2011
7:00 (PCT USA) 14:00 (GMT)
Last night I ran a repair table on the main database for CoGe. This apparently ran into some problems and failed. I am currently hunting down the problem, and the main CoGe site is currently off-line. Technically, the tools are all available, but some of them are not working. The problem appears to be located in the "locations" table of the [CoGe database]. This table records the locations for all of CoGe's Genomic features. For anyone that needs to get some work done with CoGe, they are welcome to use the development server hosted at:
This version of CoGe has been under development to federate CoGe's user authentication system with the authentication system provided by the iPlant Collaborative. As such, there has been many code changes dealing with registered users and accessing restricted/private genomes. These changes are NOT fully tested and may cause some problems. Also, the development server is using an out-of-date version of the main CoGe database (though most of the genomes should be there). If you use the development server and run into any of these problems, please feel free to send Eric Lyons an email. I'd appreciate the reporting of any bugs as well as your patience with the current situation.
In case of catastrophic failure of the main database, please know that in addition to the development server, there is a full backup of the main CoGe database. These are generated weekly.
Also, thanks to Ben Field for notifying me of the problem. I deeply appreciate the help of community members in alerting me to problems with the site as well as suggestions for making it better.
- Another "repair table" is being run on the main CoGe Database.
- Backup database is being restored on the dev server for CoGe (coge.iplantcollaborative.org). Once this is up and running, I'll point the main CoGe site to use this database and database server in case the main database has not yet been repaired.
- backup coge database has been deployed to CoGe development server, currently undergoing "optimization" (want to avoid whatever happened to the main database)
- main coge database has been repaired. Warning and update messages taken down from the website. Let me know if anyone has any problems.
CoGe Tutorial Published in Maydica:
Oct. 24th 2011
A comprehensive open-access tutorial on using CoGe has been published in Maydica: http://www.maydica.org/articles/56_183.pdf
Of all the major plant groups, the grasses, with the complete genomes of five species, are the best positioned to take advantage of comparative genomics to obtain insight into functional genetic elements. Of all the grasses, maize is the best characterized in terms of genetics, development, and evolution. We provide several examples of how the web-based comparative genomics system CoGe may be used to aid in the interpretation of the maize genome sequence. These examples include verifying gene models, identifying differences between genome as- semblies, identifying conserved non-coding sequences, identifying syntenic regions between species and poly- ploidies, and identifying homeologs within maize and orthologs between maize and other grass genomes. In addition, a comprehensive list of orthologous gene sets is provided between maize and Sorghum, foxtail millet, rice, and Brachypodium.
While the article focuses on the maize genome as its primary genome, the methods are applicable to any genome.
Correction to the Classical Maize Gene and Syntelog List
Sept. 29th 2011
Phil Stinard identified an error in incorrectly assigning classical maize genes as being present in B73. Thanks to Mary Schaeffer for passing along this information and James Schnable for correcting these in the Classical Maize Gene and Syntelog List.
The following genes are now assigned as being not present in the B73:
New options in SynMap
Sept. 12th, 2011
There are a couple of new options available in SynMap:
Force dotplot to be a square: You can find this option under the "Display Options" Tab with the line "Dotplot axes relations".
SVG Version of the Dotplot: There will be a new file, "SVG Version of the Syntenic Dotplot" to download in the "Links and Downloads" section of the results. This file will only appear if some form of synonymous rates are calculated and visualized (available under the "Analysis Options" tab").
Thanks to James Schnable for creating the SVG program for SynMap!
Potato genome added to CoGe
Sept. 3rd, 2011
Genome published: http://www.nature.com/nature/journal/v475/n7355/full/nature10158.html
The genome added was doubled the monoploid S. tuberosum Group Phureja clone DM1-3 516R44 (DM):
- unmasked: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=12277
- masked: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=12278
Please note: this version of the genome does not have annotations available.
Thanks to Will Spooner for the notification!
Brassica rapa genome added to CoGe
Sept. 3rd, 2011
Genome published: http://www.nature.com/ng/journal/vaop/ncurrent/full/ng.919.html#/group-1
Sequenced by: BGI
Brassica rapa has had a hexaploidy event subsequent to the most recent tetraploidy event in the Arabidopsis lineage.
Thanks to Will Spooner for the notification!
Cannabis sativa Pseudoassembled genome added to CoGe
Aug. 23rd, 2011
SynMap has the option to assembled one genome against another using syntenic. Such Syntneic path assemblies may be used to create a Pseudoassembly of a genome when only a contig level assembly exists. SynMap makes generating these Pseudoassemblies easy to do. Such a Pseudoassembly of the 175,000 Cannabis sativa genome was performed against the peach genome (read here to learn why peach was chosen). This pseudoassembly was reloaded back into CoGe and permits using CoGe's tools to compare the Cannabis genome at multiple levels of resolution.
To see this example: Cannabis sativa cultivar Chemdawg (marijuana)
Pseudoassemblies may be quite useful as more genomes are sequences on the cheap. Such sequencing project yield low-quality draft genomes that are usually assembled into several tens of thousands of contigs, and pseudoassemblies permit the rapid generation of large sequences that are easier to use in comparative genomic analyses.
Cannabis sativa cultivar Chemdawg (marijuana) added to CoGe
Aug. 22nd, 2011
The genome of the extremophile Cannabis sativa cultivar Chemdawg (marijuana) has been added to CoGe: http://genomevolution.org/CoGe/OrganismView.pl?oid=33804
This genome was sequenced by Medicinal Genomics (located in the Netherlands). It was sequenced with one lane of the Illumina HiSeq (2x100) platform and assembled with CLCbio’s workbench. Additional information about the assembly and genome may be found: http://www.medicinalgenomics.com/the-c-sativa-genome/
You can access Cannabis in CoGe: http://genomevolution.org/CoGe/OrganismView.pl?oid=33804
Cannabis is a member of the plant order Rosales. Of sequenced genomes in that order, the peach genome is a fantastic comparator. The reason for this is due to its high-quality sequence and assembly, and its genomic evolutionary history that does not contain any whole genome duplication event subsequent to the Eudicot paleohexaploidy shared by nearly all dicots (at least the eurosids and the astrids). As such, its genome structure is probably very similar to the common ancestor of order Rosales, and perhaps the eudicots as a whole. This likely ancestral state of the peach genome makes it quite suitable for generating a Pseudoassembly of highly fractured, low quality genome assemblies such as this Cannabis genome. CoGe's tool SynMap has an algorithm to tile contigs along any other "reference" genome in CoGe.
The Syntenic path assembly of Cannabis to the peach genome may be viewed: http://genomevolution.org/wiki/index.php/Syntenic_path_assembly#Cannabis_sativa_.28marijuana.29_v._Prunus_persica_.28peach.29
This shows the Cannabis genome sequence contains nearly the entire gene content of Peach.
Eutrema parvulum (Thellungiella parvula) added to CoGe
Aug. 17th, 2011
The genome of the extremophile crucifer Eutrema parvulum (Thellungiella parvula) has been added to CoGe: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=12242
You can read about this genome in this Nature Genetics Letter: http://www.nature.com/ng/journal/vaop/ncurrent/full/ng.889.html
New Version of Setaria italica (foxtail millet) added to CoGe
Aug. 16th, 2011
Version 2.1 of Setaria italica has been added to CoGe. This genome was obtained from JGI/phytozome: http://phytozome.net
Unmasked version: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=12240 Masked version: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=12241
Thanks to Gina Turco for the request.
New Version of Fragaria vesca (woodland strawberry) added to CoGe. This time with gene models!
Aug. 11th, 2011
Version 1.1 of Fragaria vesca (woodland strawberry) has been added to CoGe http://genomevolution.org/CoGe/OrganismView.pl?dsgid=12186 .
This version contains gene models with permits more fun with syntenic dotplots: http://genomevolution.org/r/3wdb
This dotplot is strawberry versus peach. Besides from be a great summer fruit salad, this dotplot colors syntenic gene pairs based on their synonymous mutation values. From it, it is easy to see neither genome has had an independent whole genome duplication since the Eudicot paleohexaploidy event.
Thanks to Aaron Liston for requesting this genome.
Daphnia pulex (common water flea) added
Aug. 3rd, 2011
You can get all your water flea genomics here: http://genomevolution.org/CoGe/OrganismView.pl?oid=33760
Thanks to Mike Freeling for the request.
Several bugs fixed as a result of the code update
July 29th, 2011
Additional bugs were squashed today due to the major code update to CoGe's internal services. Part of the update included further modularization of the web-services from backend services. A few programs the ancillary support programs for CoGe's web-services were not correctly being passed the base configuration file for a given web-deployment and were therefore crashing. This has been corrected, but please email Eric Lyons if any problems are encountered.
Update to GenomeList
July 29th, 2011
GenomeList has been updated to:
- include a link back to GenomeList for selected genomes. This is useful if a broad selection of genomes was made and needs to be refined.
- include a link to easily download a fasta file for a given genome
- include a link to coge_gff to generate a gff file of all Genomic features and annotation in a genome
- include a TinyURL link to regenerate the genome list. This link is found at the top of the genome list.
Example GenomeList link: http://genomevolution.org/r/3v8n
Major code update to CoGe
July 27th, 2011
CoGe has undergone a major update of its web-based system today. A few bug fixes and feature enhancements mixed in, with the major one being the addition of GenomeList for creating a list of genomes, getting an overview of their genomic content, and then sending the list to other tools (e.g. CoGeBlast).
Behind the scenes was a further modularization of the web-interface from the backend support services and modules. The primary reason for this is to enable to creation of multiple CoGe installations. There has been a few requests by people for a clade/group of organisms specific installation of CoGe. With iPlant's cyberinfrastructure support, this should be possible (providing the code-base supports it).
There were some sticking points this morning migrating server specific changes from the iPlant development server to the main CoGe server, but hopefully this didn't affect too many people. However, there is a high-likelihood of additional bugs in the system that I failed to catch! Please email Eric Lyons if you find any problem.
Otherwise, we are hoping to make a full migration to iPlant's resources in the near future. iPlant's coge server is being upgraded with some additional attached storage for continual growth of the platform.
July 4th, 2011
You can find its genome in OrganismView: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=11942
This is a very rough genome (50,000+ contigs; the largest is 470KB; 13 larger than 300KB). However, the syntenic path assembly in SynMap with the option to remove any contig that doesn't have a syntenic signal makes identifying sytnenic regions a breeze (see the above link).
See this example of micro-synteny as seen in GEvo: http://genomevolution.org/r/3oxa
Thanks to: Haibao Tang, Devin O'Connor, and Jim Leebens-Mack for requesting this genome.
July 14th, 2011
The masked version of the Palm genome has been created and added to CoGe: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=11947
Thanks to Haibao Tang for providing the masking procedure.
JGI's Eucalyptus grandis BRASUZ1 has been added to CoGe
June 30th, 2011
You can find its genome here: http://genomevolution.org/CoGe/OrganismView.pl?oid=33537 (masked and unmasked sequence)
Thanks to Josquin Tibbits for recommending this genome!
Arabidopsis thaliana resequenced genomes (C24, Bur-0, Kro-0, Ler-1) from 1001genomes.org has been added to CoGe
June 30th, 2011
The "High Quality" sequences generated by the 1001genomes project for the resequencing of several arabidopsis strains has been added to CoGe. This includes:
Thanks to Maggie Woodhouse for this suggestion!
OrganismView's Feature List display updated
June 22nd, 2011
OrganismView has a minor update for where the lists of Genomic features are displayed. The old version would display the summary list of genomic features below all the information panels. This would mean that each time a summary list was generated, it would replace the prior one. For example, if you retrieved the list first for the entire genome and second for a particular chromosome. Now, each information panel's genomic feature list appears to the right of the information summary. This allows the entire genome's feature list to be display simultaneously with the chromosome's feature list.
Broad Institute's Coccidioides group Database added to CoGe
June 21st, 2011
The entire set of sequences and associated annotations for Coccidioides has been added to CoGe. These soil fungi are pathogenic and can cause coccidioidomycosis, aka valley fever, in humans. The original data may be obtained from: http://www.broadinstitute.org/annotation/genome/coccidioides_group/MultiHome.html
And accessed through OrganismView: http://genomevolution.org/CoGe/OrganismView.pl?org_desc=Coccidioides
Thanks to Marc Orbach for suggesting and locating these genomes.
UC Berkeley Data Center Back Online
June 12th, 2011
The UC Berkeley Data Center power upgrade went smoothly. CoGe has booted up and is back online.
- James Schnable for being on duty to bring CoGe down and back up.
- The entire team at the UC Berkeley Data Center for completing such a complicated upgrade to their Center and for continually updating their clients as to the progress of the operation.
CoGe Downtime June 12th, 2011
June 3rd, 2011
CoGe will be down on June 12th due to maintenance on the power infrastructure at the UC Berkeley Data Center. We will do our best to bring CoGe back up as soon as possible.
Here is their announcement:
Description: The [UC Berkeley] campus data center has been a valuable resource for campus computing for the past seven years. Demand for this highly secure, highly available, and network-redundant facility continues to rise. The current facility has reached its power and cooling capacity and Capital Projects has initiated a major renovation project intended to increase each of these capacities, while also integrating newer, more efficient systems to help the campus achieve its long-term energy conservation goals.
As part of this effort, the replacement of some core components of the data center’s power infrastructure is required. For safety reasons, a full power outage to the data center is scheduled for Sunday, June 12, 2011, from 7:00 am to 3:00 pm. The data center will rely entirely on outside air, rather than air conditioning, to provide cooling for the duration of this period. A minimal number of systems with broad campus impact, including CalMail, CalAgenda, and the campus home page, will be provided with temporary power during this outage. In the unlikely event that the data center air temperature exceeds a level appropriate for the safe operation of equipment, some of these systems may need to be shut down as well.
The list of widely used systems that are intended to remain available is below. This list is still being finalized, so additional systems may be added as campus needs require. This list will not include systems for which departments have made separate arrangements.
Citrus genomes added
May 6th 2011
The genomes of:
- Citrus clementina (Clementine mandarin): http://genomevolution.org/CoGe/OrganismView.pl?oid=33274
- Citrus sinensis (citrus, Sweet orange): http://genomevolution.org/CoGe/OrganismView.pl?oid=33273
Have been added to CoGe. These were sequenced by JGI.
Sequenced Plant Genome Phylogeny Update
May 6th 2011
James Schnable has updated the phylogeny of angiosperms for sequenced plant genomes.
CoGe Workshop at Berkeley
Apr. 19th 2011
Here is the outline/syllabus of the workshop help at Berkeley hosted by the iPlant Collaborative, the Department of Plant and Microbial Biology, QB3-CGRL (Computational Genomics Resource Laboratory), ARS-Plant Gene Expression Center, and the Freeling lab: 2011 Berkeley Workshop
This outline contains links to specific analyses used in the workshop.
Horizontal Genome Transfer
Mar. 31st 2011
Here is a fun example of a mitochondria genome being inserted into a plant chromosome: Horizontal transfer of mitochondria genome: Horizontal transfer of mitochondria genome
Mar. 29th 2011
For those times when scrolling to the top of the screen to find the "Run GEvo Analysis!" button is too much work, a second button has been added at the bottom of the configuration box. This is quite useful when comparing >6 genomic regions.
Thanks to David Braun for this suggestion!
Bug Fix in FeatView
Mar. 29th 2011
Thanks to Damon Lisch for pointing out a bug in FeatView that was exposed by Firefox v4. This bug was also affecting Google Chrome (but not Safari). Please let Eric Lyons know of any problems you have running Firefox v4 (or other problems in general).
New tutorial for performing genomic rearrangement analyses
Mar. 11th 2011
SynMap now has support for BlastP
Mar. 7th 2011
You can now select to compare protein sequences between genomes with annotated protein coding features (CDS).
Thanks to Angelique D'Hont for the suggestion.
Cochliobolus heterostrophus C5 from JGI loaded into CoGe
Mar. 2nd 2011
You can find Cochliobolus heterostrophus C5 in OrganismView: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=11258
Both masked (by JGI) and unmasked version of the genome are available.
For a syntenic dotplot between C. heterostrophus to Pyrenophora tritici-repentis strain Pt-1C-BFP (the closest relative I could find in CoGe) please follow: http://genomevolution.org/r/2m0n
This is a neat syntenic dotplot showing extensive synteny and intrachromosomeal rearrangements (though these are both contig level assemblies).
Thanks to Daniel Lawrence for request.
Sort chromosomes by name in SynMap
Feb. 26th 2011
After a couple of requests, SynMap now has an option to sort chromosomes by name instead of by size. You can read how to set this option here.
- Angélique D'Hont from CIRAD
- James Schnable from UC Berkeley
for this suggestion.
How to load genomes into CoGe
Feb. 22nd 2011
If you have a CoGe installation, access to the main CoGe server, or just curious to know what is needed to load a genome into CoGe, here is a page on How to load genomes into CoGe. This is all run from the command line, and when CoGe's user permission data management system matures, this procedure will be made available via the web.
Giant Panda genome loaded into CoGe
Feb. 19th 2011
You can see the genome in CoGe at: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=11227
This was one of the first big genomes sequenced using only Next Generation Sequencing Technology and assembled De novo. As a result, the assembly is rather poor compared to a fully assembled genome like the dog genome. However, through comparative genomics with SynMap, identifying syntenic regions and determining that nearly full coverage was obtained is as easy as a few mouse clicks: syntenic path assembly of the WGS panda genome to the fully sequenced dog genome. This will be quite useful as more and more large genomes are sequenced using these techniques (fast, cheap, and still very useful!)
First Metagenome loaded into CoGe
Feb. 19th 2011
Technically, there is no reason why CoGe can't store metagenomes. Its core data model stores a collection of sequences that, thus far, has been organized into a genome, but can accommodate any collection of sequences. So the first metagenome was loaded into CoGe from NCBI:
And can be seen in CoGe: http://genomevolution.org/CoGe/OrganismView.pl?oid=32988

Chocolate genome gene models added
Feb. 4th 2011
Thanks to CIRAD for sharing their cacao gene models. These have been added to the Theobrama cacao genome in CoGe: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=10997 .
For an example of how these gene models may be used in whole genome comparisons, see this analysis between chocolate and peach: Chocolate-peach syntenic dotplots. It shows how the evolutionary distance between sytnenic gene pairs may be visualized to differentiate between Orthologous syntenic regions derived from the divergence of these lineages, and Out paralogous syntenic regions derived from their shared Paleohexaploidy ancestry.
Arabidopsis thaliana TAIR version 10 has been added!
Jan. 27th 2011
Version 10 of the Arabidopsis thaliana genome has been added to CoGe: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=11022
Thanks to all the work by the folks at TAIR
For a syntenic dotplot of version 9 versus version 10 of Arabidopsis thaliana (with the evolutionary distances of syntenic gene pairs calculated) see: http://genomevolution.org/r/2hiz
Chocolate genome added: from the International Cacao Genome Sequencing Consortium
Jan. 26th 2011
The genome of Theobroma cacao has been published: http://www.nature.com/ng/journal/vaop/ncurrent/full/ng.736.html
You can view this genome in CoGe at: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=10997
To view some Syntenic dotplots of Cacao: Cacao syntenic dotplots
Of note, this genome has not had any whole genome duplication events since the Paleohexaploidy event at the base of the eurosids.
Version 2 of the Maize Genome, Now With Gene Models
28 November 2010
Both the 50x super masked and unmasked versions of the B73_refgen2 maize genome are now updated with the new gene models released by maizesequence.org over thanksgiving break. The new genome annotation consists of 110,028 genes, many with alternative transcripts, which can be broken down as followes:
- 29,082 transposon related genes
- 17,615 putative pseudogenes
- 63,276 "real" genes. Please note while these genes were annotated as "protein coding" in the current release, they include predicted microRNA genes.
Sept. 16th 2010
CoGe's servers have successfully be moved to a new rack space. Thanks to James, Bao, and Brent for making this happen.
Pending CoGe Maintenance
Sept. 15th 2010
We have received word from the UC Data Center which houses CoGe that we need to move our servers to a new rack space. This should only take an hour or two. Our tentative schedule time for the move is:
Sept 16th 2010 at 1pm (PCT)
We apologize for any inconvenience this may cause any of CoGe's users.
Aug. 26th 2010
Organisms selected in SynMap have links in their taxonomic descriptions. If you click on a term in the taxonomic description, that term is automatically entered into the organism description search. All organisms with a matching taxonomic term will be displayed. This makes it faster to find organisms related to the one in which you are interested.
Aug. 26th 2010
OrganismView now has more links for finding information about an organism, and to internal CoGe tools.
External searches under organism information:
Internal CoGe links:
- CodeOn: automatically generates a table of amino acid usage as a function of the GC content of CDS sequences.
- SynMap: (under Genome information) automatically loads SynMap with both genomes specified to the one selected. This makes is quick to start generating whole genome comparisons and Syntenic dotplots.
Home Page update
Aug. 26th 2010
CoGe's homepage menu "Latest Genomes" now has links to search for the organism name in
- CoGe's OrganismView
This makes it quicker to find information on an organism, specifically if you have no idea what it is. Helpful considering that there are nearly 9,000 organisms in CoGe.
Aug. 26th 2010
CoGeBlast now has support for specifying blastn, tblastx, lastz, megablast, and discontinuous megablast when searching with nucleotide sequences.
10,000th genome loaded!
Aug. 4th 2010
Brassica rapa has been added to CoGe and represents the 10,000th genome loaded in CoGe. Its sequence was generated by the BGI located in China. This relative of Arabidopsis is a wonderful addition to sequenced plant genomes. Their lineage share a series of whole genome duplication events (commonly known as alpha, beta, and gamma -- the latter happening prior to the radiation of the eudicots). Since their divergence, Brassica rapa has had a triploidy while Arabidopsis has had none.
Genome update from NCBI
June 28th 2010
A new update of genomes from NCBI has finished. This includes genomes from all domains of life. CoGe now has genomic sequence from 8,872 organisms comprising 9,999 genomes. There is also a new option on the homepage to list the most recently added genomes.
SIP 2010 workshop syllabus
June 23rd 2010
The syllabus for a day-long workshop on how to use CoGe for the Society for Invertebrate Pathology's conference (SIP 2010) is now available. This workshop focuses on:
- Getting an overview of how CoGe is designed for allowing scientists to create their own open-ended analyses
- Learning what the various tools in CoGe do and they to use them
- Working through specific sets of example problems focused on analyzing two groups of organisms important for invertebrate pathology: baculoviruses and Bacillus thuringiensis
The workshop's syllabus is available: SIP2010
CoGe's update progress
June 18th 2010
The switch to the new server went as smoothly as I could have hoped.
Besides from new hardware (which should greatly accelerate many of CoGe's analyses and improve system stability), this installation welcomes a new version of CoGe too!
This new version of CoGe has:
- Update UI
- Various feature extensions on existing tools
- Updated algorithms (new blast API with support for the megablast families, LastZ)
- New database additions
- Update of core modules for database API
- New configuration files that will help deployment of CoGe to new sites
Please contact Eric Lyons if you find any bugs!
Today is the day
June 17th 2010
Going to through the switch today. Expect some downtime with CoGe and some support systems being temporarily off line.
New CoGe Server Update
June 10th 2010
It appears that most of the software updates and migration to the new server are working. We have deployed the new server to the UC Data Center, but due to some complications with rack-space, IP address allocation, sub-nets, firewalls, etc., things may be in flux for a while. We've had to take our development server (aka toxic) off line and put the new server on its IP address till those things get sorted out. In the meanwhile, we will plan on making the switch to production on the new server soon (hopefully next week). When this happens, expect CoGe to be offline for a couple of hours, but we will do our best to keep downtime to a minimum.
New CoGe Server is being readied!
June 2nd 2010
We have our new server for CoGe! Its deployment will not only include new performance improvements due to more computing power, but all several changes and additions to CoGe:
- new user interface
- new algorithm options
- new structure of the underlying code-base to make it is easier to redeploy (in anticipation of eventually getting the code-base released to those interested)
We are planning on moving the new server to the UC data center this Fri. After some more testing and bug hunting, we will switch our current production server's IP address to this machine. There is a high chance that there will be some downtime for CoGe during this switch and we will post announcements as to when this change will happen! In the meanwhile, if anyone is interested in testing new CoGe, please e-mail Eric Lyons.

New NCBI Genome Update. CoGe surpasses 8,900 genomes from 8,200 organisms
Apr. 9th 2010
Finished an update from NCBI. However, this is not a complete listing of all genomes available at NCBI due to some API problems getting some genomes. You can read about this problem below.
Version 3 of Medicago truncatula added to CoGe
Apr. 9th 2010
You can view the genome in CoGe at: http://genomevolution.org/CoGe/OrganismView.pl?dsgid=8976
Syntenic comparison of version 3 to version 2 shows extensive changes in the primary sequence. Some chromosomes have had their sequence substantially updated.
Prunus persica (peach tree) added to CoGe
Apr. 9th 2010
You can view its genome in CoGe at: http://www.genomevolution.org/CoGe/OrganismView.pl?oid=30980
Its genome was produced by the International Peach Genome Initiative and its sequence was obtained from phytozome. This genome is currently unpublished and therefore under the publication restrictions of the Fort Lauderdale Convention.
Peach is a eudicot in the Rosaceae family.
Automatic NCBI Genome Loader Update
Apr. 8th 2010
The automatic NCBI genome loader is running today. It has been a while since I last ran it after running into an API problem with NCBI's eutils tools three months ago. The issue is still unresolved and even after checking in every two weeks for a status update, I have yet to receive any word as to when the bug will be fixed. For those interested, here is my bug report sent at the end of January:
Issue (http://jira.be-md.ncbi.nlm.nih.gov/browse/HD-1843): Key: HD-1843 Summary: Unable to get some genomes using eutils Type: Task Status: In Progress Priority: Normal Assignee: Matten, Wayne Reporter: Nobody Description: Hi, I've be checking which genomes are available from NCBI using eutils by getting a list of all the genome project ids (genomeprj) and then retrieving their associated genome ids. I've found that a lot of the recently deposited genomes (usually with accessions CPXXXXXX) are have a genomeprj id but no associated genome id. For example, genomeprj=30031. It is listed in this list: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=genomeprj&term=all%5Bfilter%5D&retmax=999999 But has no genome id: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?db=genome&dbfrom=genomeprj&id=30031 However, it does have an entry in genbank: http://www.ncbi.nlm.nih.gov/nuccore/CP001637.1?ordinalpos=3&itool=EntrezSystem2.PEntrez.Sequence.Sequence_ResultsPanel.Sequence_RVDocSum I am probably missing something obvious. Can you help me figure out how to get a list of all the genomes at NCBI? I am using these data in an NSF funded and publicly available comparative genomics platform (http://synteny.cnr.berkeley.edu/), and have programs that check for new genomes and new versions of existing genomes from NCBI on a periodic basis. It is important for this system to be as up to date as possible with regards to the large number of genomes that are becoming available as there are many researchers using this tool for their work. Thanks in advance for your help, -Eric Lyons
If anyone has any solutions to this problem, please contact me.
Major bug fix in SynMap
Mar. 26th 2010
While testing the prior bug fix, I discovered that SynMap wasn't working on genomic sequence comparisons (as opposed to CDS sequence comparisons). This was due to the new analytical pipeline's data processing requiring unique names for each blast hit. Otherwise, multiple hits to the same sequence name would get removed as a Local duplicate. As all hits to a genomic sequence were named according to the chromosome, all such hits were flagged as Local duplicates and removed from the analysis.
As always, if you find a problem in CoGe, feel free to email Eric Lyons and let him know what you've found. There are now too many options and buttons to click in CoGe for me to test with each update.
Minor bug fix in SynMap
Mar. 25th 2010
With SynMap's new analytical pipeline, there are still some bugs to be worked through. Hopefully got one today in the script that converted blast input files to bed format, which is required for the program to find local duplicates in the compared genomes. These local duplicates are removed from the algorithm for finding collinear series of putative homologous genes used to infer syntenic regions. Also, these local duplicate files are displayed in the download section of the results in case they are wanted for other analyses.
Hosting local tiny URL encoding
Mar. 24th 2010
Replaced using tinyurl.com for a local installation of a URL hashing and redirecting service. Makes generating these faster and allows for customized names. Note: the tinyurls will still work.
Mar. 13th 2010
James Schnable has created a page detailing all of the sequenced plant genomes including:
- overview of their genomic content
- status of completion
- interesting factoids (e.g. The average US American eats 25lbs of bananas a year.)
Read about them here: Sequenced plant genomes
The JGI's Manihot esculenta (cassava) genome has been added
Mar. 13th 2010
The JGI's Cucumis sativus (cucumber) genome has been added
Mar. 12th 2010
You can access it in CoGe here. Or get more information about it from phytozome. This is apparently a distinct sequence from the one in Nature Genetics last November. That sequence was from "'Chinese long' inbred line 9930" this version comes from the inbred Gy14. More details here
Mar. 12th 2010
After a month of work, SynMap has undergone several significant changes, incorporating new algorithms written by Haibao Tang and Brent Pedersen:
- new merging function for overlapping and neighboring diagonals (program: quota alignment)
- new method for detected tandem gene duplicates
- better reporting of all intermediate files used in the analysis, including tandem duplicates
These changes have also hoped to increase the stability of SynMap, which due to its long pipeline, has been known to crash for some genomes and/or specific parameter configurations. Please let Eric Lyons know if you have any problems with an analysis. Please send along the names of the organisms/genomes compared and a copy of the log file produced by each SynMap run (if possible).
Persistent GEvo bug fixed
Mar. 11th 2010
However, if anyone does come across this bug again (or any others), please let me know: Eric Lyons
Rice Version 6.1 loaded
Mar. 10th 2010
The classic set of Maize Genes
Mar. 9th 2010
James Schnable manually evaluate ~460 classic maize genes available from MaizeGDB and NCBI, determined their genomic positions in the maize genome, and found their Syntenic regions within maize (from its most recent Whole genome duplication event), sorghum, rice, and brachypodium. This list contains links to compare these syntenic regions using GEvo.
New plant genomes in CoGe
Feb. 10th 2010
Mimulus guttatus (monkey flower): http://synteny.cnr.berkeley.edu/CoGe/OrganismView.pl?oid=30760 Mimulus is an outgroup to the rosids (in the sister group, the asterids)
Populus trichocarpa (Poplar; cotton wood): http://synteny.cnr.berkeley.edu/CoGe/OrganismView.pl?oid=324 Version 2 of poplar!
Both are from the JGI.
Feb. 8th 2010
MaizeGDB is now linking to CoGe's GenomeView so maize researchers can find maize-sorghum Syntenic gene sets and quickly perform syntenic analyses using GEvo. For an example view from MaizeGDB's genome broswer:
For instructions on how to perform this workflow: MaizeGDB and CoGe

Syntelog visualization in GenomeView
Feb. 5th 2010
GenomeView has been updated to auto-detect Genomic features with annotations that are links to GEvo. These links provide an analysis of a Genomic feature (e.g. gene) to previously identified Syntologous sets of features. Currently, this has been implemented using syntelogs from maize and sorghum, but with the code in place, we will expand annotations for genomic features from other organisms for which we generated syntologous gene sets. For an example of this visualization in GenomeView please see: | this GenomeView of sorghum. Also, for an expanded list of glyphs used in GenomeView please refer to these examples.
Easy exporting and downloading of genomes
Jan. 16th 2010
OrganismView has new options for easily downloading the sequences of a genome in fasta format and retrieving all of its annotations in an GFF file. To access, just search for an organism and genome of interest, and look for the links under "Genome Information".
Jan. 10th. 2010
We've linked to phylogeny.fr for quick and easy phylogenentic tree reconstruction. Now, you can build a list of fasta sequences and display them in FastaView, select protein or DNA sequences, edit them if necessary (e.g. add or remove sequences manually), and press a button to send them off to phylogeny.fr for:
- multiple sequence alignment (MUSCLE)
- maximum likelihood phylogenetic tree reconstruction (PhyML)
- tree visualization (TreeDyn)
For an example, use this link to FastaView and press the button "phylogeny.fr" at the bottom of the screen.
Special thanks to Haibao Tang for pointing out this incredible web resource!

Improved implementation of DAGChainer in SynMap
Dec. 15th 2009
Thanks again to Brent Pedersen for some fantastic programming. He discovered that DAGChainer's C++ code's makefile did not include the -O3 optimization, rewrote the input/output methods of the compiled binary to read from STDIN instead of a file, and rewrote the perl front-end in python. Together, these changes increase CoGe's DAGChainer implementation in SynMap between 2-4 fold.
You can download his code at: svn co http://bpbio.googlecode.com/svn/trunk/scripts/dagchainer
