The PhiPack software package implements a few tests for recombination and can produce refined incompatibility matrices as well. Specifically, PHIPack implements the 'Pairwise Homoplasy Index', Maximum Chi2 and the 'Neighbour Similarity Score'. The program Phi can be run to produce a p-value of recombination within a data set and the program profile can be run to determine regions exhibiting strongest evidence mosaicism.
