Hi,
You should be able to- you'll just have to be careful when making your
ligand, receptor and complex file and be careful not to strip out the water
molecules that you want to preserve, usually by renaming the water atoms to
something other than WAT.
What impact it'll have on the energy is hard to say- I've only ever seen
people keep specific water atoms for MMPBSA in DNA/RNA complexes. If
nothing else, I'd do it once without the waters, and then again with the
waters just to have a point of comparison.
Best,
Kenneth

Ask yourselves, all of you, what power would hell have if those imprisoned
here could not dream of heaven?
