[Bioperl-l] Help with taxonomy db

[Jason Stajich]

The source => 'flatfile' is right you can either use 'flatfile' or 
'entrez' as the source.

I think there may have been bugs in one of the released versions of the 
module where it doesn't properly re-open the index.  I know I fixed 
something in this after the 1.4 release but I don't remember what was 
the exact problem.

I'd see if bioperl 1.5.0 code still gives the problem.
