Application Details

• Description: BayesTraits
• Version: 3.0.0 (supplied compiled binaries)
• Modules: bayes/3.0.0 (apps)
• Licence: Free

Introduction

BayesTraits is a computer package for performing analyses of trait evolution among groups of species for which a phylogeny or sample of phylogenies is available.

This new package incorporates our earlier and separate programs Multistate, Discrete and Continuous.

BayesTraits can be applied to analysing traits that adopt a finite number of discrete states, or to analysing continuously varying traits. Hypotheses can be tested about models of evolution, ancestral states and correlations among pairs of traits.

Multi-Batch Jobs

The following job script will automatically run 3 identical BayesTrait jobs in an array so that three outputs can be compared. It takes care of separating the jobs, running them, and then bringing the outputs together.

#!/bin/bash
#SBATCH -J BayesTrait_array
#SBATCH -N 1
#SBATCH  -n 28
#SBATCH -o %N.%j.%a.out
#SBATCH -e %N.%j.%a.err
#SBATCH -pcompute
#SBATCH --exclusive
#SBATCH --array 1-3
 
module add bayesTraits/3.0/intel-2017
 
# Create 3 sub-directories inside which each job will run
RUNDIR=`pwd`
mkdir $SLURM_ARRAY_TASK_ID
cd $SLURM_ARRAY_TASK_ID
 
# Update here to set command, tree, and data files 
COMMAND_FILE=MCcSM_RJHPexp05_WCLCBNoZero_command.txt
TREE_FILE=FritzHARD_WCLCBNoZero.trees
DATA_FILE=MCcSM_RJHPexp05_WCLCBNoZero.txt

# Make a 'copy' of the command, tree and data files in the job sub-directories
ln -s ../$COMMAND_FILE .
ln -s ../$TREE_FILE .
ln -s ../$DATA_FILE .
 
BayesTraitsV3 $TREE_FILE $DATA_FILE < $COMMAND_FILE
 
cd $RUNDIR
 
# Copy the output files from each of the 3 run directories into a file called run_1_<data_file>.log.txt
cp $SLURM_ARRAY_TASK_ID/${DATA_FILE}.Log.txt run_${SLURM_ARRAY_TASK_ID}_${DATA_FILE}.Log.txt
