Thanks for the reply Dr. Justin. I have also thinking of the same possibility but to further confirm, I am sending the link for the plot of the distance between the COM of ligand binding pocket and COM of ligand molecule, please find some time to have a look at the plot and let me know if it seems a feasible behaviour during a simulation.
