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

I'm using a tool called AnnotationSketch (part of the GenomeTools package)
to create graphics from my GFF3 files. It complains when sequence-region
lines are not included, even when the reference is printed as a feature.
That's what got me interested in the problem in the first place.
Thanks for the info, I'll figure something out.
