Good day everyone, I am currently trying a workflow that was done with blastall version 2.2.26. I wanted to update it and use the 2.8.1 version of blast that we have. I have this one parameter that I am confused with. I'm currently trying to produce a tabular output (blastall -m 8 , blastn -outfmt 6), with the parameter -v (Number of database sequences to show one-line descriptions for (V)) for blastall and -num_descriptions in blast 2.8.1 is not compatible with 2.8.1 version of blast with a tabular format. I seem to not understand what exactly this does and how it affects my output. Can anyone help me understand this?
outfmt 6, does not provide descriptions summary, so only the
-num_alignments is relevant.
The old blastall was a bit more lenient towards those two parameters, the blast+ suite is more strict on it
and I personally prefer
-max_target_seqs in tabluar context
