CoRe-PA

CoRe-PA Overview

CoRe-PA is a tool for reconstructing the coevolutionary history of host parasite systems. As Tarzan it uses an event-based method to find cost minimal reconstructions. These events are cospeciation, sorting, duplication and (host)switching.

With CoRe-PA you can:

• design host parasite scenarios with a graphical editor
• generate random coevolutionary scenarios using the beta-split model with beta 0, -1 or -1.5
• generate random coevolutionary scenarios by simulating coevolution
• generate random coevolutionary scenarios which “keep the character” of given host parasite systems
• handle non-binary host and parasite phylogenies
• choose between different behaviors of how to handle switches
• use divergence timing information
• compute the best reconstructions for a given set of costs
• compute the best cost vector for a given host parasite system (where the cost vector fits best to the reconstructed event frequencies)
• do randomization tests for given host parasite systems to analyze the probability of coevolution
• export host parasite scenarios and their reconstructions to svg
