TreeStat is an application that can process a set of trees in a PHYLIP or NEXUS format tree file and calculate a number of summary statistics for each. These are saved in a tab-delimited file for analysis in Tracer or statistics packages. A range of summary statistics are included: Tree-Balance Statistics. Colless*s, B1, N_bar, cherry count. Tree shape.Tree height, node heights, treeness, Pybus* gamma. Population genetic. Fu & Li*s D, external or internal ratio. Other.Tree length, root-to-tip lengths.

BEAST is fast, flexible software for Bayesian analysis of molecular sequences related by an evolutionary tree. BEAST implements a family of Markov chain Monte Carlo (MCMC) algorithms for Bayesian phylogenetic inference, divergence time dating, coalescent analysis, phylogeography, andrelated molecular evolutionary analyses. This package includes an enhanced graphical user interface program called BayesianEvolutionary Analysis Utility (BEAUti) that enables access to advanced models for molecular sequence and phenotypic trait evolution. The package also provides new tools for visualizing and summarizingmultispecies coalescent and phylogeographic analyses.
