Re: Subroutine to parse BLAST

[umasuresh]

I recommend reading Beginning Perl for Bioinformatics. Along with the book the author provides a module  BeginPerlBioinfo.pm which has subroutine  extract_HSP_information showing how to parse BLAST result. This is a good starting point for your task.

Yes, that is THE book for learning Perl for bioinformatics - well written and definitely a "must have" for the beginner. But I would add that it's only a good starting point if you want to a) follow the lesson for the purpose of learning Perl or b) really, really can not possibly use BioPerl in your environment. In all other cases, BioPerl is the way to go.
