Brownie Description

Character evolution models, species delimitation, and tree search Brownie is a free and open source application for analyzing rates of continuous character evolution and looking for substantial rate differences in different parts of a tree using likelihood ratio tests and Akaike Information Criterion (AIC) statistics.Brownie can read Nexus tree and data files and can perform analyses across a set of weighted input trees (such as trees weighted by posterior probabilities or bootstrap values) in order to deal with tree uncertainty. While Brownie deals with subtrees (and uses the censored test of O'Meara et al), Sanderson's r8s program can output rate estimates for sets of edges or individual edges and is needed for the non-censored test.
