Unfortunately fasterq-dump does not support a clip option, but the older fastq-dump does.
In general, without reproducing the options used, you can't compare the result of two runs of fastq-dump
or fasterq-dump
. Does EBI document what options they used when generating the fastq file you downloaded from them?
Is there a reason you need clipping in fasterq-dump
besides reproducing the file from EBI?
We discovered, that fastq files downloaded from NCBI SRA via fasterq_dump are different to the ENA stored fastq files. After some digging, this is probably due to the
--clip
option.Example downloaded from: https://www.ebi.ac.uk/ena/browser/view/DRR010705
Default download via fasterq_dump
Unfortunately, there seems to be no
clip
parameter for fasterq-dump. Any idea how to generate identical reads as the ones stored in ENA ?See also: https://github.com/galaxyproject/tools-iuc/issues/6171 as we're trying to use that for Galaxy.
