- 18/04/15 Migrating from Gna! to Github.
With the CoMap package, you can perform the following tasks:
- Compute probabilistic substitution maps, possibly with biochemical weights (comap)
- Compute coevolution statistics (correlation, compensation) for all pairs of sites (comap)
- Test for significance of pairwise statistics using parametric bootstrap (comap)
- Cluster sites according to a coevolution distance (correlation, compensation) (comap)
- Test for significance of groups using parametric bootstrap (comap + R script)
- Perform correction for multiple testing with group statistics (R script)
- Test if given candidate groups of sites are significantly coevolving (comap)
- Compute mutual information (MI) based statistics for all pairs of sites (mica)
- Test significance of MI statistics using various methods (mica)
- Advanced test of significance of MI statistics, accounting for site-specific substitution rates (mica + R script)
The CoMap package can be compiled from source, or installed from packages for various Linux Systems (including Ubuntu, Fedora, Suse). Standalone binary executables are also available for Linux (32 and 64 bits). On MacOSX, CoMap is available via Homebrew. More information can be found on the wiki.
The documentation of the program can be browsed here. A PDF version of the manual can be downloaded from here.
Example data sets are distributed along with the source code. The 'simple' analyses example contain the minimal set of options required. For more advanced usage, the user can look at the example analyses from the 2007 paper. All examples are updated as the program options change.
