[Bioperl-l] Out of memory errors running Bio::ASN1::EntrezGeneagainst latest Homo_sapiens.ags file

[Susan Wilson]

Mingyi,

Thank you very much for your advice.  The text ASN file 1/4 the size  
of the (evil, evil) XML file and parsing it ran just fine.  We are  
still pursuing a 64-bit perl on our 256GB server and I will let you  
know how it works.

Thanks.
Susan
