[Bioperl-l] Write segments with Bio::Tools::GFF

[Scott Cain]

Hi Daniel,

Why do you need the sequence-region line?  It is mostly just
informational.  If you want to define the reference sequence for the
features in the GFF file, I would suggest printing out a full GFF line
for the reference sequence instead anyway.  That way, it can have all
the information that a GFF line can encode, like a source and type, as
well as information in the ninth column.

That said, Bio::Tools::GFF probably does lack that method.  The code
in it is probably a little outdated.
