[Bioperl-l] taxonomy db flatfile: get taxon from gi?

[shalabh sharma]

Hi Anna,
           I think the thread you mentioned was started by me.
That time i wrote few scripts to map gi to taxa, after some time i found
some other efficient ways also. But recently 'Miguel Pignatelli' directed
to some Bio-LITE modules that are really helpful.

These are the modules he mentioned, i found them really easy to use and
very efficient.

Bio-LITE-Taxonomy-0.07
Bio-LITE-Taxonomy-NCBI-0.07
Bio-LITE-Taxonomy-NCBI-**Gi2taxid-0.04

Cheers
Shalabh
