Available

  • Roihu: 2.1, via the bio-apps module.

Usage

ClustalW is part of the bio-apps collection on Roihu. Load the bio-apps module tree and then the ClustalW module:

module load bio-apps/v202603
module load clustalw/2.1

The program is run with the clustalw2 command. For example, to align sequences in a file:

clustalw2 -infile=sequences.fasta -outfile=aligned.aln

Example batch script

#!/bin/bash
#SBATCH --job-name=clustalw
#SBATCH --account=<project>
#SBATCH --output=output_%j.txt
#SBATCH --error=errors_%j.txt
#SBATCH --partition=small
#SBATCH --time=04:00:00
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --cpus-per-task=1
#SBATCH --mem=4G

module load bio-apps/v202603
module load clustalw/2.1

clustalw2 -infile=sequences.fasta -outfile=aligned.aln

Replace <project> with your CSC project (for example project_2001234).
