[Bioperl-l] Bio::Graphics::Glyph->parts differences between 1.636 and 1.654

[Oliver Burren]

Thanks Lincoln. I overrode maxdepth and set it to 1. I assume that this
is more efficient than setting to undef ?

perl test_parts.pl
Top level feature contains 100 features
Bio::Graphics::Panel API is 1.654 <----
Bio::Graphics::Glyph::testparts.pm can find 100 parts.

So problem solved. I am intrigued though as you said there were two
things, I was just wondering about the second thing ?

Thanks for your help.
