[Bioperl-l] Bio::Tools::Blast.pm & unacceptable memory usage

Hi,

I am new to using bioperl and would like to parse large numbers of blast
reports.  I read at:
http://doc.bioperl.org/bioperl-live/Bio::Tools::Blast

Parsing large numbers of Blast reports (a few thousand or so) with
Bio::Tools::Blast.pm may lead to unacceptable memory usage situations.
This is somewhat dependent of the size and complexity of the reports.
...snip...
When using the parse_blast.pl or parse_multi.pl scripts in
examples/blast/ of the bioperl distribution), don't supply
a -signif command-line parameter.


I tried to run parse_multi.pl with -signif 1e-25 and the job died.  Is
there a fix for this problem?

regards,

Charles
