Hi

Something I stumble one from time to time: the storage of sequence in AlignIO
is based in SeqIDs. This complicated reading alignments with duplicate IDs,
which actually do occur quite a lot (e.g. CDD of NCBI). Usually I try to
"uniqfy" IDs but this is not straightforward for all alignments formats.
Actually this is were BioPerl is really useful ;-)
I'd propose to store the Sequences in a hash in AlignIO using unique keys,
possibly optionally, to be able to read all sequences in the alignment, even
when they all have the same ID.

This would solve the replacing warnings too.
-------------------- WARNING ---------------------
MSG: Replacing one sequence [10/1-214]

Possibly this can be taken in with the AlignIO refactoring

Regards,
Bernd
