are you simulating DNA? that's a DNA tutorial.
I strongly suggest that you don't just follow a tutorial designed to tech
you how to change certain flags (and in the end I believe the tutorial
suggests that this GB model does not work well in the example) but follow
instead the literature. find one or more articles that successfully do what
you are trying to do. read their methods carefully. then, use the tutorials
to help you understand which specific flags will let you use a method such
as that outlines in the article. a good article will tell you all of the
options that they set, including the radii set that was used (look at the
Leap manual for PBradii- they are used for GB as well).
