  • Phylogeny of genomes with polyploidy events marked

Sample Datasets

To access sample datasets

Setting the hook: getting data loaded into CoGe

  • Loading new genomes into CoGe
    • Loading genomes into the Bio.ci (iPlant Data Store) for the first time
      • Sign up for an account or log in
      • Access the Data Store
      • Direct upload from your computer
        • Press the upload tab on the top left and select 'Simple upload from Desktop'
        • Find the genome(s) FASTA file and select
        • Enjoy a picnic outside while they upload
      • Using FTP/HTTP links for uploading genomes in the Data Store
        • 1) In the top left of the screen click on the 'Upload' button
          • a) Select 'Import using URL'
          • b) This will create several spaces to paste URLs into so that the Data Store will retrieve files (in this case genome FASTA files/.fa files). Once the blank areas come up, open a new tab in your browser
        • 2) copy the link location of the genome FASTA file from an FTP site or webpage
        • 3) paste the URL into a blank on the Data Store page
        • Enjoy some tea or coffee while they upload
    • Once the genomes have been uploaded into the Data Store
      • Select them and move them into the folder names 'coge_data'
      • The genome should now be visible in the CoGe platform
    • Direct upload

  • OR Use genomes already available in CoGe

Casting the Line: analyses for comparing genomes

Whole genome syntenic analysis

  • SynMap (tutorial)
    • Identify Whole Genome Duplications
      • Example 1: Whole genome synteny analysis of Oncorhynchus mykiss (rainbow trout) compared to Takifugu rubripes. In this analysis, the synonymous mutation rate (Ks) has been calculated to determine the relative age of each syntenic gene pair (represented as a dot) in the dotplot. The blue/green color indicates a newer whole genome duplication whereas the red/orange dots are noise in the dataset. The histogram below the dotplot shows the distribution of the synonymous mutation rates

Microsyntenic analysis

  • GEvo
    • Validate microsynteny
      • Example 1: Microsynteny analysis using GeVo to compare T. rubripes to O. mykiss. This analysis shows evidence of whole genome duplication in O. mykiss (the Salmonid WGD) when compared to another Teleost fish that does not have a WGD after the Teleost WGDfff.
    • Identify Conserved non-coding sequences (regulatory function)

Ortholog/paralog finding with synteny

  • SynFind
    • Identify orthologous regions across many species

Sinkers to Cast Further and Deeper: adding weight to genomes with additional data types

Adding new data (genomes, RNASeq, SNPs) to CoGe

Gene family analysis

  • CoGeBlast
    • Identify many gene family members within/across species
    • Extract sequences (nucleotide/protein)
    • Phylogenetic tree reconstruction using iPlant/iAnimal for multiple sequence alignment and tree building

Functional genomics

  • Adding/visualizing RNAseq data
