Fluctuations in proteins

 Dear Netters.
 I am interested in using average fluctuations during a
 specific time as a method for examing the quality of
 different MD-simulations. Does anyone know if this has
 been done since Morgan, McCammon and Northrup in 1983.
 The only later paper I know that discussed this is by
 Post, Dobson and Karplus in 1989.
 None of these papers discuss any thoretical origin
 of the time dependence of these fluctuations.
 I guess that some polymer scientists know more about this than I do.
 I would appreciate any references that can give insight
 into theories that discuss this subject.
 sincerely Arne Elofsson
