beast description

BEAST is a cross-platform program for Bayesian analysis of molecular sequences using MCMC which allows construction of complex dated phylogenetic trees (phylogenies). It is entirely orientated towards rooted, time-measured phylogenies inferred using strict or relaxed molecular clock models. It can be used as a method of reconstructing phylogenies but is also a framework for testing evolutionary hypotheses without conditioning on a single tree topology. BEAST uses MCMC to average over tree space, so that each tree is weighted proportional to its posterior probability. We include a simple to use user-interface program for setting up standard analyses and a suit of programs for analysing the results.

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.
