Data download using module load sra-tools

Aim:

Download FASTQ files for samples of interest.

SRA website: https://www.google.com/search?client=safari&rls=en&q=NCBI++SRA&ie=UTF-8&oe=UTF-8

Search NGS data of interest

In the ‘search box' enter one of the following identifiers:

Project accession (i.e., PRJNA229998)
Study accession (i.e., SRP033351)
Experiment accession (i.e., SRX384360)
Run accession (i.e., SRR1039508)
or search for keywords, for example, “RNA-seq mouse”

Prepare a list of SRA run accessions to be downloaded and saved in a file, for example, ‘SRR_Acc_List.txt’:

SRR1039508
SRR1039509
SRR1039510
SRR1039511
SRR1039512

Prepare a PBS Pro submission script as follows:

#!/bin/bash -l
#PBS -N rna
#PBS -l select=1:ncpus=1:mem=8gb
#PBS -l walltime=24:00:00

#Enable the container modules
source /pkg/shpc/enable
#Load the SRA-TOOLS module
module load sra-tools/3.0.5--h9f5acd7_1
#work on current directory (folder)
cd $PBS_O_WORKDIR

for i in $(cat SRR_Acc_List.txt);
do
  echo $i
  prefetch.3 $i
  fasterq-dump.3 --split-files $i
done

gzip *fastq

submit PBS script to the HPC cluster

qsub launch_fetch_SRAfiles.pbs
