What is BEAST?

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

This website is for BEAST v1.X (currently version v1.8.4). For details about BEAST2, an independent project led by the University of Auckland, please look here.

Introductory Tutorials

These tutorials use the graphical applications of BEAST to perform analyses using the provided example files:

Tutorial 1: Using sequences sampled at different points in time to estimate rates Tutorial 2: Estimating the divergence time of a monophyletic group using a known mutation rate And more Tutorials available.

Some downloadable packages containing tutorial worksheets and associated data. These are used in workshops and classes.
