PMID: 24926665. GEO: GSE52778.

From the abstract, a brief description of the RNA-Seq experiment on airway smooth muscle (ASM) cell lines: “Using RNA-Seq, a high-throughput sequencing method, we characterized transcriptomic changes in four primary human ASM cell lines that were treated with dexamethasone - a potent synthetic glucocorticoid (1 micromolar for 18 hours).

Fetching FASTQ files from SRA

Install the sra-tool kit if not yet installed. For example:

#Create a conda environment
conda create -n sra -c bioconda sra-tools
conda activate sra

Save a list of SRA accession numbers to download in a file called SraAccList.txt

SRR1039508
SRR1039509
SRR1039510
SRR1039511
SRR1039512

Use the following PBS Pro submission script to fetch the FASTQ files for all listed samples. Note, data will be downloaded to the folder where the job is submitted. Example script (fetch_SraAccList.pbs):

#!/bin/bash -l
#PBS -N sra_fetch
#PBS -l walltime=8:00:00
#PBS -l mem=8gb
#PBS -l ncpus=4
#PBS -m bae
###PBS -M email@host
#PBS -j oe

#Usage: qsub fetch_SraAccList.pbs

cd $PBS_O_WORKDIR

for i in `cat SraAccList.txt`;
do 
  echo $i
  prefetch $i
  fastq-dump --split-files $i  
done
