The BreakDancer package provides genome-wide detection of structural variants from next generation paired-end sequencing reads.
Program breakdancer-max predicts five types of structural variants: insertions, deletions, inversions, inter- and intra-chromosomal translocations from next-generation short paired-end sequencing reads using read pairs that are mapped with unexpected separation distances or orientation.
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 breakdancer [user@cn3144 ~]$ bam2cfg.pl bam_file1 bam_file2 %BreakdancerOptions% > config_file.cfg [user@cn3144 ~]$ breakdancer-max config_file.cfg > file.ctx [user@cn3144 ~]$ exit salloc.exe: Relinquishing job allocation 46116226 [user@biowulf ~]$
Create a batch input file (e.g. batch.sh). For example:
#!/bin/bash set -e module load breakdancer breakdancer-max config_file.cfg > file.ctx
Submit this job using the Slurm sbatch command.
sbatch batch.sh
Create a swarmfile (e.g. job.swarm). For example:
cd dir1; breakdancer-max config_file.cfg > file.ctx cd dir2; breakdancer-max config_file.cfg > file.ctx cd dir3; breakdancer-max config_file.cfg > file.ctx
Submit this job using the swarm command.
swarm -f job.swarm --module breakdancerwhere
-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 | Loads the module for each subjob in the swarm |
