[Bioperl-l] Fetching Fasta seqs from GenBank - Help request

[Alberto Davila]

Hi,

May I ask for some help ?

I am trying to use the BioFetch module in order to download several seqs
(from specific Organisms) from GenBank in fasta format, but looks like I
am missing "IO/String.pm" and other things.. should I install additional
bioperl modules (I have the Bioperl Core 1.4 installed) ? or use a
different module for my purpose ?

My script and error msg are listed below.

Thanks and besr regards,

Alberto
