Description

"Basic Local Alignment Search Tool, or BLAST, is an algorithm for comparing primary biological sequence information, such as the amino-acid sequences of different proteins or the nucleotides of DNA sequences." More details are at BLAST+

Running Program

The last version of this application is at /usr/local/apps/eb/BLAST+/2.6.0-foss-2016b-Python-2.7.14

To use this version, please load the module with

ml BLAST+/2.6.0-foss-2016b-Python-2.7.14

Here is an example of a shell script, sub.sh, to run on the batch queue:

#!/bin/bash
#SBATCH --job-name=j_BLAST+
#SBATCH --partition=batch
#SBATCH --mail-type=ALL
#SBATCH --mail-user=username@uga.edu
#SBATCH --ntasks=1
#SBATCH --mem=10gb
#SBATCH --time=08:00:00
#SBATCH --output=BLAST+.%j.out

cd $SLURM_SUBMIT_DIR
ml BLAST+/2.6.0-foss-2016b-Python-2.7.14
blastn [options]

In the real submission script, at least all the above underlined values need to be reviewed or to be replaced by the proper values.

Please refer to Running_Jobs_on_the_teaching_cluster, Run X window Jobs and Run interactive Jobs for more details of running jobs at Teaching cluster.

Here is an example of job submission command:

sbatch ./sub.sh
