        This tool extracts reads from SRA archives using fastq-dump.
        The fastq-dump program is developed at NCBI, and is available at
        http://www.ncbi.nlm.nih.gov/Traces/sra/sra.cgi?view=software.

        NB: Single-end or pair-end collections may be empty if given SRRs LibraryLayout contains only either SINGLE or PAIRED respectively
