Spanner is a c++ program for the detection of Structural Variation events from whole genome sequenced read pair data. It uses aligned read information in bam format and was developed in conjunction with the Mosaik alignment program

/usr/local/spanner/src

biowulf% module load spanner

1. Create a script file similar to the one below

#!/bin/bash
# This file is called spanner.bat
#
#PBS -N Spanner
#PBS -m be
#PBS -k oe

module load spanner

cd /data/user/somewhereWithInputfile

3. Submit the script using the 'qsub' command on Biowulf.

Using the 'swarm' utility, one can submit many jobs to the cluster to run concurrently.

Set up a swarm command file (eg /data/username/cmdfile). Here is a sample file:

module load spanner; spanner -i file1 -Z -M mask1.file -t      
module load spanner; spanner -i file2 -Z -M mask2.file -t      
module load spanner; spanner -i file3 -Z -M mask3.file -t      
module load spanner; spanner -i file4 -Z -M mask4.file -t      

Submit this swarm with:

swarm -f cmdfile

By default, each line of the commands above will be executed on 1 processor core of a node and can use 1GB of memory. If each spanner command requires more than 1 GB of memory, you should specify the memory require for each spanner command (i.e. each line of the swarm command file above) by using the -g flag:

For more information regarding running swarm, see swarm.html

User may need to run jobs interactively sometimes. Such jobs should not be run on the Biowulf login node. Instead allocate an interactive node as described below, and run the interactive job there. For example:

biowulf% qsub -I -l nodes=1 
qsub: waiting for job 2236960.biobos to start 
qsub: job 2236960.biobos ready
      
[user@p4]$ module load spanner

[user@p4]$ cd /data/user/somewhereWithInputfile 
[user@p4]$ spanner -t -Z 1 -u -M mask.file
[user@p4] exit 
qsub: job 2236960.biobos completed 

[user@biowulf ~]$ 

User can add a node property in the qsub command to request a specific kind of interactive node. For example, if you need a node with 8gb of memory to run job interactively, do this:
