Downloading data from the SRA website

Download SRA file with prefetch (of SRA toolkit which uses ascp (-t fasp)

# Use prefetch (SRA toolkit) to download SRA file:
#   - SRA files will be written to: $HOME/ncbi/public/sra/
#   - If your HOME dir is constrained in space, make a symlink:
#       ln -s /dir_with_lots_of_free_space/ncbi ${HOME}/ncbi
prefetch -v -t fasp SRR5353377

# Convert SRA file to gzipped FASTQ files with fastq-dump (SRA toolkit).
