Hi,
I found this line in psl.pm:
my $score = sprintf "%.2f", ( 100 * ( $matches + $mismatches + $rep_matches ) / $q_length );
However, from the BLAT program documentation:
-minScore=N sets minimum score. This is twice the matches minus the mismatches minus some
sort of gap penalty. Default is 30
It seems to me that the score computed in psl.pm should be based on something more like
this:
100 * (2* $matches - $mismatches + $rep_matches) / $q_length
