[Bioperl-l] [Bioperl]problem with E-value

[Chris Fields]

I pretty sure I know exactly what the problem is and how to fix it  
(if you haven't done it already).  Looks like the parser trashes the  
rest of the BLAST results data since it's not catching the next BLAST  
report header (and not breaking out of the while() loop).  That may  
be what is triggering the e-value error.  I have been parsing new  
BLAST reports recently w/o that one popping up, but it may be a  
difference between the web BLAST report and the executable (wouldn't  
be the first time that has happened.

Did you want me to take a look?
