CoMap 1.4.1

:: DESCRIPTION

CoMap performs two kinds of tasks:

(Weighted) Probabilistic substitution mapping – Compute all (weighted) number of substitutions occurring on each branch of a tree, for each site of an alignment.
Co-evolution analysis – Using the substitution mapping, look for significantly groups of sites departing the null hypothesis of independence. Two kind of analyzes are provided: a pairwise analysis, presented in Dutheil et al. (2005), and a clustering analysis in Dutheil and Galtier (2007). In both cases, a parametric bootstrap approach is used to evaluate the significance of groups. Simulation results are written to separate files, a statistics software like R is required to look for the significance.
