Hello all, I've been long troubled with redundant blast hits from different strains of the same species, for example, E. coli. These hits (can be dozens to hundreds) mask hits from other species which I'm more interested in. So I wonder if there's a way to have blast return only one hit from one species? Thanks!
PS: I'm quite okay with writing a script to filter BLAST hits to one-hit-per-species after I got the hits. But my goal is to do so on BLAST itself by manipulating its parameters, so that the hits are already filterred on the server side. So I don't have to face a BLAST hit table with all 100 hits saying "E. coli"
