Hi! I'm using prefetch command from SRA Toolkit on HPC cluster to download SRA data, but got stuck into error:

2020-03-26T16:34:59 prefetch.2.10.0 int: transfer incomplete while reading file within network system module - Cannot KStreamRead: https://sra-downloadb.be-md.ncbi.nlm.nih.gov/sos2/sra-pub-run-13/SRRXXXXXXX/SRRXXXXXX.X


How can i fix that?

Thaks for your reply. I don't run them in parallel, but sequentially one by one inside one for loop. Before prefetch running i've executed:

/home/sratoolkit.2.10.0-ubuntu64/bin/vdb-config -s /http/timeout/read=1000000000


It seems that above command helps but not in all cases.

This tutorial here covers download directly in fastq format from ENA but be aware that ENA is performing maintenance work right now so download might not be possible. Fast download of FASTQ files from the European Nucleotide Archive (ENA)

Thanks a lot. Will try different solutions.

Besides, i should to note that initially i have approximately 60 accessions and got error with prefetch only for 11 of them (everything were fine with the rest ones). Then i ran again exactly the same prefetch command for these 11 accessions and downloaded half of them (for 6 got error).
