Dear Amber Users,

Have any of you put planarity restraints on NA bases during any kind
of restrained MD? I have noticed during our simulated annealing with
NMR restraints, some of the bases are bending in unusual ways - in
particular the N on the glycosidic bond of the Cytosine base. I have
played around with putting some restraints on that particular bond but
I would like to know what others have tried.
