[Bioperl-l] Newbie StandAloneBlast - too many files?

i am using the latest version of biperl (i have the administator upgrade it
less than a week ago)... and i did notice that StandAloneBlast does have
it's own destroy function but I never tried calling the cleanup function
manually.  The files are deleted from the /tmp/ dirctory after each round of
blasts (2 per loop).  I'll try the _io_cleanup.  currently i just reduced
the number of sequences in each run to 20 and call the script multiple
times...

thanks
