sbatch example

This description assumes that above step ( prepare software ) were done beforehand.
Bellow slurm job creates temporary folder in your home folder (like tmp.AtrQrrJi3W), then downloads file 090413_I352_FC31307AAXX_L6_SORssqRADDHAAPE_1.fq.gz and run it with AdapterRemoval software. This job will take about 10 minutes, inspect job output ex.: slurm-1949.out for AdapterRemoval output messages.

File adapterremoval_test.batch :

#!/bin/bash -l
#SBATCH --partition=test
#SBATCH --ntasks=2
#SBATCH --mem 4G
#SBATCH --job-name AdapterRemoval_test

#prepare temporary folder
cd `mktemp -d -p ~/`

#download fq file
wget wget ftp://download.big.ac.cn/SorghumVB/fastq/090413_I352_FC31307AAXX_L6_SORssqRADDHAAPE_1.fq.gz

#export path to AdapterRemoval binary
export PATH=$PATH:/home/users/${USER}/anthill23_soft/adapterremoval-2.3.1/build

#use AdapterRemoval software
AdapterRemoval --file1 090413_I352_FC31307AAXX_L6_SORssqRADDHAAPE_1.fq.gz --qualitybase 64
