BioPerl

Introduction

BioPerl is a collection of Perl modules that facilitate the development of Perl scripts for bioinformatics applications. It has played an integral role in the Human Genome Project.

Installed version

The currently installed version is 1.7.0.

Using BioPerl

If you want to use BioPerl on the cluster, you will have to load its corresponding module first. You can do that with the command:

module load BioPerl

After that BioPerl is loaded and operational.

Using BioPerl on the cluster

If you want to run jobs on the cluster, you will have to create a jobscript which needs to be submitted to SLURM.

An example jobscript for BioPerl could look like this:

#!/bin/bash 

#SBATCH --ntasks=1
#SBATCH --mem=2G
#SBATCH --time=0-2:00  
#SBATCH --job-name=BIOPERL-TEST
#SBATCH --output=bioperl-test.%j.out        
#SBATCH --error=bioperl-test.%j.err   

module load BioPerl
perl seqio.pl

If you want to run this example, please create a file with the bioperl-test.job containing the code above. You will also need to create a file called "seqio.pl" with the following content:

#!/bin/perl -w

use Bio::Seq; use Bio::SeqIO; 

$seq_obj = Bio::Seq->new(-seq=>"aaaatgggggggggggccccgtt",
                         -display_id => "#12345",
                         -desc => "example 1",
                         -alphabet => "dna" ); 

$seqio_obj = Bio::SeqIO->new(-file => '>sequence.fasta',
                             -format => 'fasta' ); 

$seqio_obj->write_seq($seq_obj);

If you created both files you can submit your job with the following command:

sbatch -p carl.p bioperl-test.job
