Getting StartedĪs BEAST 2 is such a large and complicated application, first-time users may find coming to grips with the program and its capabilities a daunting task. For a comparison of features/models currently available in BEAST 2 with those currently implemented in BEAST 1, refer to this features table. As a result, BEAST 2 has rapidly acquired the ability to perform a diverse array of model-based analyses.

This makes it easier to extend BEAST 2 via its package system. Version 2īEAST 2 is a rewrite of BEAST 1.x, placing a greater emphasis on modularity. Previous releases and version history are available on the BEAST2 releases web page. The XML reference is available in the online manual. The BEAST 2 source code is available from the GitHub repository, which produces the latest cutting edge jar file here: beast.jar. Older versions are available from the BEAST2 releases web page. If you download a version of BEAST without Java, you need to install Java separately (for OS X, JDK 8 is recommended). Select one of the following to download the version for your operating system:Īfter this, or if you already have v2.6.X (X=0, 1 or 2) installed, you can upgrade via the package manager. The latest version of BEAST 2 is version 2.6.6. BEAST 2 includes a graphical user-interface for setting up standard analyses and a suit of programs for analysing the results. BEAST 2 uses Markov chain Monte Carlo (MCMC) to average over tree space, so that each tree is weighted proportional to its posterior probability. 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. It estimates rooted, time-measured phylogenies using strict or relaxed molecular clock models. BEAST 2 is a cross-platform program for Bayesian phylogenetic analysis of molecular sequences.
