Hi everyone,
Could anyone explain in a little bit more details what's the difference for the options max_target_seqs
and num_alignments
. If I only want the top hit, how to do in BLAST setting?
Thank you very much!
I am afraid that is not what max_target_seqs does: https://academic.oup.com/bioinformatics/advance-article/doi/10.1093/bioinformatics/bty833/5106166
See https://blastedbio.blogspot.com/2018/11/blast-max-alignment-limits-repartee-one.html and https://blastedbio.blogspot.com/2018/11/blast-max-alignment-limits-repartee-two.html for more details - all of
-max_target_seqs
,-num_descriptions
and-num_alignments
set an internal limit during the search as well as limiting the output.Thank you, Siva. Your comment is really helpful.
