[Bioperl-l] Fetching > 500 sequences

[Lincoln Stein]

There may be a bug in Bio::DB::GenBank, or Entrez may have changed its 
behavior again very slightly.  The interface between the two has always been 
quite fragile.  At some point I will work on this again and try to get it 
working, but first.... Have you tried the bioperl-live CVS version?
