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.

Execution Environment and Modules

To use beast with the environment modules system at HPC the following commands are available:

Get module information for beast:

$module spider beast

Load the default application module:

$module load beast

The modulefile for this software adds the directory with executable files to the shell execution PATH and sets the following environment variables:

  • HPC_BEAST_DIR - directory where beast is located.
  • HPC_BEAST_BIN - executable directory
  • HPC_BEAST_DOC - docs directory
  • BEAST - Beast directory


Beast is also available for use through the friendly web interface of the UF HPC Galaxy instance. It's located in the "Phylogenetics" section.

Interactive beauti use

Template:Connect test05 Once connected run

module load beast

How To Run

  • To use the beagle library use the '-beagle_SSE -beagle_instances N' command line switches where 'N' equals to the number of requested Beagle library instances.
  • To limit the number of computing cores Beast will use for posterior computation to the number requested from the batch system use the '-threads N' where 'N' is the number of threads.
