[Bioperl-l] bl2seq error when no alignment

[Julio Fernandez Banet]

Hello.
I'm parsing bl2seq using BPbl2seq. My problem comes when only of my
sequences didn't give me any alignment and the program crashes with the
following error message:
Can't call method "nextHSP" on unblessed reference at
/Library/Perl/Bio/Tools/BPbl2seq.pm line 242, <GEN79> line 31.

I place lots of check lines in my code and I the program crashes when
reaching this line:
 while(my $hsp = $report->next_feature) {

Should I change or add something so the program doesn't crash when there's
no sequence alignment?.

Thanks a lot for your help.

P.S.
The file that give the error is:
