BEAST 2
=======

[![Build Status](https://github.com/CompEvol/beast2/workflows/Core%20tests/badge.svg)](https://github.com/CompEvol/beast2/actions?query=workflow%3A%22Core+tests%22)

BEAST is a cross-platform program for Bayesian inference using MCMC 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.
