[Bioperl-l] Retrieve FASTA seqs with NCBI definition line

[Heikki Lehvaslaiho]

Mikaela,

I do not think there is a shortcut and I do not think modifying the the
way fasta is processed from the sequence information is a good idea. So
many things depend on it. You have to manually modify the return values
of methods: display_id() and  desc().

Assuming you go ahead and do it, could you put the code into a function
(seq2NCBIfasta  ? ) which could be added into Bio::SeqUtils?

Then anyone needing to do the same thing could:

$out = Bio::SeqIO->new(-format => 'fasta');
$out->write_seq(Bio::SeqUtils->seq2NCBIfasta($seq));

Cheers,
	-Heikki
