Hi Saman,
Check out the GIST or GRID features in cpptraj (the GIST tutorial on the amber website is really good: http://ambermd.org/tutorials/advanced/tutorial25/). If you're only interested in checking the number of waters, I think just using either the "hbond" command or a combination of "closest" and "distance" in cpptraj, should work. You could use that either for histograming the water populations, or as a dataset to apply via "filter", to obtain the snapshots in your trajectory which are in your favorite hydration state.
I hope this helps,
Manuel

Subject:[AMBER] Plot activesite water vs time.
Dear All,
I have a trajectory file and I would like to plot the number of water molecules within a distance from a ligand in time or study thermodynamicproperties of the water clusters over trajectory. I've been trying to figure out how to do it via cpptraj but I couldn't find anything.
I hope you can help me.
Thanks,Saman
