Yes, I do notice this in my MD simulations of DNA. It is probably related
to the force constants in the out-of-plane (improper) torsion terms of the
force field, but if one takes an average MD structure these deviations
should cancel out. Also, any MD structure probably needs to be
energy-minimized before further calculations, and this also should restore
base planarity.
Hope this helps.
