[Bioperl-l] Blast return codes

[Matthew Laird]

This is on the fringe of being off-topic... but still relivant. :)

I've been trying to google around to find documentation regarding return
codes Blast gives upon exit.  Is there a list of return codes and
conditions that cause non-zero return codes?

The reason I ask is I'm having a problem calling Blast from bioperl.  For
some reason Blastall is returning a -1 exit code which of course causes
bioperl to throw an exception.  However I have modified my local install
of bioperl to tell me the exact command that was being run.  I've then run
this exact command with the exact same input files from the command line
and a standard 0 exit code is returned.  Might anyone have any thoughts on
why Blastall would be returning a -1 exit code?

Thanks for any assistance you might be able to provide.
