[Bioperl-l] extract feature seq when split between 2 GenBank accessions

[Charles Hauser]

All,

I'd like to extract the CDS from genbank records and have found that in
some instances these are distributed among >1 genbank accession (see
below).

I have a script which does fine if CDS is fully contained within 1
accession, other than storing all accession seqs in a hash is there a
good way to deal with these?
