BEAST

module avail beast/
module avail beast2/

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.

Usage

Parallel run

For parallel running, additional parameters are required

-instances N -threads N

where N is the number of processors requested in the PBS task. And also add

useThreads="true"

attribute in the input file.

With BEAGLE

# Load BEAST, e.g.
module add beast2/beast2-2.6.7-intel-19.0.4-d2lg5zn
# Load OpenJDK
module add openjdk/openjdk-1.8.0_222-b10-intel-19.0.4-xc66unh
# Load BEAGLE
module add libbeagle/libbeagle-3.1.2-intel-19.0.4-gpu-m62lgl6

Beast additional packages

Users can install additional packages available via the packagemager command in their home directories. The following example demonstrates the local building of Beast 2.7.7 (distributed as a binary file; no installation is required) and the installation of the SNAPP package. 

$ wget https://github.com/CompEvol/beast2/releases/download/v2.7.7/BEAST.v2.7.7.Linux.x86.tgz
$ tar -xf BEAST.v2.7.7.Linux.x86.tgz
$ export PATH=/storage/city/home/user_name/beast/bin/:$PATH

The default installation of Beast includes only Beast and Java.

$ beast -version
BEAST v2.7.7
---
BEAST.app v2.7.7
BEAST.base v2.7.7
BEAST.app v2.7.7
BEASTLabs v2.0.2
---
Java version 17.0.3

If the SNAPP package is installed in the same directory as Beast itself, the package will be detected automatically.

$ packagemanager -add SNAPP -dir /storage/city/home/user_name/beast
$ beast -version
BEAST v2.7.7
---
BEAST.app v2.7.7
BEAST.base v2.7.7
BEAST.app v2.7.7
SNAPP v1.6.1
BEASTLabs v2.0.2
---
Java version 17.0.3

But if the package is located in a different (non-automatically detected) path, it is necessary to specify this path via the -packagedir option in the beast command.

$ beast -packagedir /storage/city/home/username/folder_with_packages
