DIA-NN on Biowulf

DIA-NN is an application used to process mass spec proteomics data using high-throughput methods. According to the authors:

DIA-NN - a universal software suite for data-independent acquisition (DIA) proteomics data processing. Conceived at the University of Cambridge, UK, in the laboratory of Kathryn Lilley (Cambridge Centre for Proteomics), DIA-NN opened a new chapter in proteomics, introducing a number of algorithms which enabled reliable, robust and quantitatively accurate large-scale experiments using high-throughput methods. DIA-NN is currently being further developed in the laboratory of Vadim Demichev at the Charité (University Medicine Berlin, Germany).

Important Notes

Interactive job
Interactive jobs should be used for debugging, graphics, or applications that cannot be run as batch jobs.

Allocate an interactive session and run the program.
Sample session (user input in bold):

[user@biowulf]$ sinteractive --cpus-per-task=4 --mem=16G
salloc.exe: Pending job allocation 46116226
salloc.exe: job 46116226 queued and waiting for resources
salloc.exe: job 46116226 has been allocated resources
salloc.exe: Granted job allocation 46116226
salloc.exe: Waiting for resource configuration
salloc.exe: Nodes cn3144 are ready for job

[user@cn3144 ~]$ module load diann

[user@cn3144 ~]$ cd /data/$USER/project # change this path accordingly

[user@cn3144 project]$ diann --threads $SLURM_CPUS_PER_TASK \
  --fasta input.fasta \
  --cfg config_file \
  --out report.tsv \
  --dir output_dir

[user@cn3144 project]$ exit
salloc.exe: Relinquishing job allocation 46116226
[user@biowulf ~]$

Batch job
Most jobs should be run as batch jobs.

Create a batch input file (e.g. diann.sh). For example:

#!/bin/bash
set -e
module load diann
diann --threads $SLURM_CPUS_PER_TASK \
  --fasta /data/$USER/project/input.fasta \
  --cfg /data/$USER/project/config_file \
  --out report.tsv \
  --dir /data/$USER/project/output_dir

Make sure to update the paths according to your need. Then submit this job using the Slurm sbatch command.

sbatch [--cpus-per-task=#] [--mem=#] diann.sh
Swarm of Jobs
A swarm of jobs is an easy way to submit a set of independent commands requiring identical resources.

Create a swarmfile (e.g. diann.swarm). For example:

diann --threads $SLURM_CPUS_PER_TASK --fasta input1.fasta --cfg config.txt --out report1.tsv --dir outdir
diann --threads $SLURM_CPUS_PER_TASK --fasta input2.fasta --cfg config.txt --out report2.tsv --dir outdir
diann --threads $SLURM_CPUS_PER_TASK --fasta input3.fasta --cfg config.txt --out report3.tsv --dir outdir
diann --threads $SLURM_CPUS_PER_TASK --fasta input4.fasta --cfg config.txt --out report4.tsv --dir outdir

Submit this job using the swarm command.

swarm -f diann.swarm [-g #] [-t #] --module diann
where
-g # Number of Gigabytes of memory required for each process (1 line in the swarm command file)
-t # Number of threads/CPUs required for each process (1 line in the swarm command file).
--module diann Loads the diann module for each subjob in the swarm
