[Bioperl-l] Extracting sequences from Genbank files

[Roy Chaudhuri]

Isn't it "get_tag_values" not "each_tag_value"? Maybe you are using an 
old version, in which case you should probably upgrade to the most 
recent BioPerl (1.6.901). You could also look at "get_tagset_values", 
which does not throw an error if the tag is not present, so saves having 
to call has_tag.

Cheers,
Roy.
