Quick question, probably already asked (sorry in this case).

How can i set "Max target sequences" in NCBI BLASTn equal to 1? The minimum value I can set from the website is 10...

Thank you all for the help and for the attention.

word of caution: do not use the max-target parameter without reading up on it. It may (/will) not always work as you expect it to be. For more info google around for it. Here (https://blastedbio.blogspot.com/2015/12/blast-max-target-sequences-bug.html) is a good start.

Perhaps what you really want is to set "-num_alignments" to 1 ?
