Where does this come from, please? In the SeqFeatureI documentation it
says seq_id 'is an attribute such that you *can* store the ID' (my
emphasis). You seem to be saying that if I'm creating a bunch of (sub)
features just so I can use Bio::Graphics, I must attach a seq_id to each
and every one.
I have an inverse question that I haven't managed to find an answer to
yet. If I'm displaying these sub-features as segments, how can I attach
some text to the feature that will be displayed alongside each
