Genometools on Biowulf
The GenomeTools genome analysis system is a free collection of bioinformatics tools (in the realm of genome informatics) combined into a single binary named gt. It is based on a C library named libgenometools which contains a wide variety of classes for efficient and convenient implementation of sequence and annotation processing software.

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 --mem=5g 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 genometools [user@cn3144 ~]$ gt -help Usage: bin/gt [option ...] [tool | script] [argument ...] The GenomeTools genome analysis system. -i enter interactive mode after executing 'tool' or 'script' -q suppress warnings -test perform unit tests and exit -seed set seed for random number generator manually. 0 generates a seed from current time and process id -help display help and exit -version display version information and exit Tools: bed_to_gff3 cds chain2dim chseqids clean ... ...

Batch job
Most jobs should be run as batch jobs.
Create a batch input file (e.g. gt.sh). For example:
#!/bin/bash set -e module load genometools cd /data/$USER gt bed_to_gff3 -force yes -o out.gff3 input.bed
Submit this job using the Slurm sbatch command.
sbatch --mem=5g gt.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. gt.swarm). For example:
cd dir1; gt bed_to_gff3 -force yes -o out.gff3 input.bed cd dir2; gt bed_to_gff3 -force yes -o out.gff3 input.bed ... cd dir10; gt bed_to_gff3 -force yes -o out.gff3 input.bed
Submit this job using the swarm command.
swarm -f gt.swarm -g 5 --module gtwhere
-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 gt | Loads the gt module for each subjob in the swarm |
