For this script to work properly, you should have gbs folder in your home directory, and jobs and projects folders inside gbs

  • Once you have the full script copied in a simple text file with extension .sh, the name variable should be replaced with something more explicit, such as your project name.
  • Keyfile should have these 4 mandatory headers: 'Flowcell' 'Lane' 'Barcode' 'FullSampleName'

To keep everything organized, I recommend using the same base name for the project and the files, for example

name = projectName

Keyfile name = projectName.txt

Shell script name = projectName.sh

  • Once the Keyfile and shell script are ready, put them in jobs folder and run qsub projectName.sh


#!/bin/bash
 
# Update the user and name variables, user is your K-State eID. Also use update the email id to get notification about the job.
user=eID
name=projectName
#$ -m abe -M eID@ksu.edu
 
# Update beocat resources request
#$ -l h_rt=72:00:00 -l mem=64G -l nokillable -cwd

If everything ran correctly, you should get a folder named projectName in your gbs/projects folder with all the output files including SNPs containing projectName.h5 and projectName.hmp.txt files that can be used for further analyses
