Subject: [AMBER] MSD of ligand??

HI
MSD = mean square displacement
diffusion coefficient = d/dt (MSD)

I simulate the protein and ligand system and then calculate the MSD of the ligand.
Then, i drew the plot of the time evolution of the MSD.
But the the MSD decreases as time for some period.

I see nothing about my codings.
Would you please tell me about any possible errors i made?
Thank you
Lin
