[Bioperl-l] Bio::Assembly::IO problems - FIXED!

[Florent Angly]

As far as I know, there really isn't a specification of the ACE file 
format, that would rule if it is legal to have the kind of contig name 
(non capitalized), other that its original implementation in Phrap.
According to the spirit of the ACE file format, my guess is that any 
contig name should be allowed. For example, on this webpage 
http://www.cbcb.umd.edu/research/contig_representation.shtml, the contig 
name is just a number.
So please Russel file this as a bug so that the developers can keep 
track of this bug,
Regards,
Florent
