If you pass in the -alphabet option to Bio::SeqIO you can prevent the
sequence object from needing to guess its alphabet.
See the Bio::SeqIO perldoc:
Sets the alphabet ('dna', 'rna', or 'protein'). When the alphabet is
set then Bioperl will not attempt to guess what the alphabet is. This
may be important because Bioperl does not always guess correctly.
