[Bioperl-l] e-value from RemoteBlast differs from hand made b last

[Martin Schenker]

Might be a stupid question, but have you checked that you are using the same
BLAST version and database in both instances?

The BLAST version is given in the first line of the output like:

TBLASTN 2.2.1 [Apr-13-2001]

The database stats are given below the Query:

Database: /scratch/db/my_strange_db
           719,859 sequences; 375,894,912 total letters

Best, Martin
