AxParafit: Highly optimized and parallelized version of Parafit.

What do the Programs do?

AxParafit and AxPcoords are highly optimized versions of Pierre Legendre's Parafit and DistPCoA programs for statistical analysis of host-parasite coevolution. AxParafit has also been parallelized with MPI (Message Passing Interface) for compute clusters. We have used parallel AxParafit to carry out the largest co-evolutionary analysis to date for the paper describing the software.
