PLINK/SEQ on HPC

PLINK/SEQ is an open-source C/C++ library for working with human genetic variation data. The specific focus is to provide a platform for analytic tool development for variation data from large-scale resequencing projects, particularly whole-exome and whole-genome studies. However, the library could in principle be applied to other types of genetic studies, including whole-genome association studies of common SNPs.

Plink/Seq was developed at Harvard University

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@biowulf]$ sinteractive
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 plinkseq
[user@cn3144 ~]$ pseq ex1.vcf v-view --vmeta --gmeta

[user@cn3144 ~]$ 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. batch.sh). For example:

#!/bin/bash
set -e
module load plinkseq
pseq ex1.vcf v-view --vmeta --gmet

Submit this job using the Slurm sbatch command.

sbatch batch.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. job.swarm). For example:

cd dir1; pseq ex1.vcf v-view --vmeta --gmet
cd dir2; pseq ex1.vcf v-view --vmeta --gmet
cd dir3; pseq ex1.vcf v-view --vmeta --gmet

Submit this job using the swarm command.

swarm -f job.swarm --module plinkseq
