CopyCat provides an easy and fast access to cophylogenetic analyses.
It incorporates a wrapper for the program ParaFit, which conducts a statistical test for the presence of congruence between host and parasite phylogenies. CopyCat offers various features, such as the creation of customized host-parasite association data and the computation of phylogenetic host/parasite trees based on the NCBI taxonomy.

Use of the program is free for academic purposes at an academic institute. For all other uses, please contact the authors.
