[Bioperl-l] Fetching particular tags of genbank/genpept features via eutils

[Jason Stajich]

More likely you want another place to ask the question - biostars perhaps - http://www.biostars.org/

if you were only searching genomes you could perhaps grab the ptt files from the FTP site - though you would need to lookup GI ids to get the ACC number for the NP_XX which is a bit convoluded and I'm not sure you can round trip.

But the produce descriptions for the genomes like in bacteria are in these .ptt files.
ftp.ncbi.nih.gov:/genomes/Bacteria/Yersinia_pestis_A1122_uid158119/NC_017169.ptt
