I have done the MD simulation of protein in water. Now I want to do the clurster entropy distribution of protein. Can anyone tell me how to do this using gromacs or any other method?
If one assumes that a structural cluster corresponds to a system's microstate, then S = kB Sumi(pi log(pi)), where kB is the Boltzmann constant and pi is the probability for the system to be in the i-th microstate (i.e., cluster). The probabilities can be readily calculated from the cluster populations.
