Bayesian Evolutionary Analysis by Sampling Trees

BEAST 2

BEAST is a cross-platform program for Bayesian MCMC analysis of molecular sequences. 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.

NOTE: This directory contains the BEAST 2 source code, and is therefore of interest primarily to BEAST 2 developers. For binary releases, user tutorials and other information you should visit the project website at www.beast2.org.
