you might look at an example of this analysis that we did for a single
protein using MD

**Wickstrom, L., Bi, Y., Hornak, V., Raleigh, D. and Simmerling, C.,
the Solution and X-ray Structures of the Villin Headpiece Helical Subdomain:
Molecular Dynamics Simulations and Double Mutant Cycles Reveal a Stabilizing
Cation-Pi Interaction"*, Biochemistry, 46:3624-3634 (2007)

also Levy's group (and others) has done more extensive analysis of
differences between
xray and nmr structures, though I am not sure of large-scale studies using
