Using CoGe to help with Genomic Rearragement Analyses is quite simple:

  1. Go to SynMap
  2. Select two genomes
  3. Select the "Analysis Options" tab
  4. Optional: Set the "Merge Syntenic Blocks" algorithm to [[Quota align] and set some number of allowable overlapping genes (10-20 works well for microbes, select 80 for large animal and plant genomes)
  5. Set the "Syntenic Depth" algorithm to Quota align and have the ratio of syntenic depth set to 1:1
  6. Run SynMap
  7. Use the link "Rearrangement Analysis" located under the "Links and Downloads". This will take you to GRIMM for the genomic rearrangement analysis
  8. Run GRIMM


Configuring a SynMap analysis to use Quota align with a syntenic depth of 1:1.
Syntentic dotplot between two species of Escherichia. X-axis: coli B strain REL606; Y-axis: fergusonii strain ATCC 35469. Syntenic dotplot has boxes drawn around syntenic regions and there is a link to GRIMM for rearrangement analysis. The link to GRIMM will only show if the quota align algorithm has been set and set to a 1:1 ratio. Results may be regenerated at http://genomevolution.org/r/2nd7
