...Evaluate statistical distributions of internal variables:
a. single variable distributions (including the most relevant in the atomistic representation, e.g. PHI and PSI and a number of those for the Cα based representation)
b. two variables correlations (including the PHI-PSI Ramachandran map and its equivalent in the Cα based representation)
c. three variables correlations
