[Bioperl-l] EMBL format field

Wed Jun 11 01:43:55 UTC 2008

This can be accomplished using IdConvert if protein accession/gi is known:

$> ./IdConvert.exe BAA19060
#Input  Nuc_GI  Nuc_Acc Pro_GI  Pro_Acc Desc
BAA19060        1783121 AB000170.1      1783123 BAA19061.1     
endopeptidase 24.16 type M3 [Sus scrofa]

Download IdConvert from http://www.genenformics.com/download.html for free.
