[gmx-users] Monitoring the water movement during simulation

I tracked the movement of water molecules around residues 65 to 67 of my
protein (GFP crystal structure) .. According to the literature water should
not enter the protein (reason being the cage like structure of GFP) .. but
in VMD, 2 water molecules have been tracked to interact with chromophore ...
So , I am a bit confused as it should not have happened ?? ... For my
analysis I need to check whether the water is entering the protein or not
.. Since I have simulated some variant structures (long loops) of GFP and I
need to check how this structure would or would not lead to the entrance of
