[Bioperl-l] BLAST parsing Question

[Brian Osborne]

Leonardo,

Good point. Another useful document is bioperl.pod which lists and briefly
describes all the example code in the examples/ and scripts/ directories.
There's close to 100 scripts in these two directories.

Dear Simon,

I encourage you to read the bioperl tutorial

http://bio.perl.org/Core/bptutorial.html

The module to use is BPlite. For usage see:

http://docs.bioperl.org/releases/bioperl-1.0/Bio/Tools/BPlite.html
