[Bioperl-l] Getting UTRs

[Michael Muratet]

Greetings

This may be a question for the database partners who define features (I
did ask Genbank), but here it is:

When dealing with a record that has a CDS feature (which may have
introns) and no mRNA feature, how does one (or bioperl) deal with the
UTRs? Is it as simple as the first base of source to the first base of
CDS for 5' and the last base of CDS to the last base of source for 3'?
The answer I got from Genbank was in terms of an mRNA feature. What if
there isn't one?

Cheers

Mike
