We are very excited to announce that we are moving to incorporate the amazing JBrowse viewer into CoGe's GenomeView feature. Click here to see a demo of JBrowse displaying a genome with lots of quantitative data sets. This feature is still under development (translation: there are still some major bugs), but in the coming month we will be working out the kinks and adding new features.

The LoadGenome feature now has an improved way to specify a new organism in the system. The new NCBI taxonomy browser allows you to search for the NCBI name and description for an organism and modify it if needed.
Feb. 8th, 2013
Many further improvements and bug fixes have been made to the data management features in CoGe for loading and share private genomes. This upgrade marks a major change in the system that allows you to share your data with individual users as well as user groups. If you haven't seen it yet, check out the new user profile page (login required) that allows you to load and share your own genome sequence and quantitative data in CoGe. We have some ideas on further improving these features and will be working on them over the next few weeks.
Jan 12th, 2013
We presented a computer demonstration of the new User Data Management features in CoGe at the Plant and Animal Genome conference today. Here are the slides.

Happy new year! Development continues on the EPIC-CoGe Browser. An overview of the project and information on progress will be posted: here.
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.

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:
Sept 24th, 2012
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:
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.

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.

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

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.

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.

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.

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.
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 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.

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.

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).

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.

The UC Berkeley Data Center power upgrade went smoothly. CoGe has booted up and is back online.
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.

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!)

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:

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.

CoGe's servers have successfully be moved to a new rack space. Thanks to James, Bao, and Brent for making this happen.
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.

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:

CoGe's homepage menu "Latest Genomes" now has links to search for the organism name in
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.
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.
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.

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:
Please contact Eric Lyons if you find any bugs!
June 17th 2010
Going to through the switch today. Expect some downtime with CoGe and some support systems being temporarily off line.
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.
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:
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.

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.

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.
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.
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.

After a month of work, SynMap has undergone several significant changes, incorporating new algorithms written by Haibao Tang and Brent Pedersen:
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).

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 a quick video walk through of the new connections: MaizeGDB_and_CoGe.27s_Maize-Sorghum_Orthologies
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.
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:
For an example, use this link to FastaView and press the button "phylogeny.fr" at the bottom of the screen.

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.
