[Bioperl-l] OBDA/Flat question

[Brian Osborne]

Bioperl-l,
I've been playing with OBDA and everything works well, and the notion of
unifying all one's sequence retrievals with a single user interface is an
excellent one. My question concerns Bio::DB::Flat. Is there a way of
specifying substrings in the fasta header as ids, analogous to id_parser()
in Bio::Index::Fasta and the -makeid option in Bio::DB::Fasta?
It seems I'm forced to use strings like "gi|48882|emb|CAA41428.1|" as ids.
Thanks again,
Brian O.
