It should not make any difference.

We need to know what commands you used. If you stripped the waters first,
you would need to construct a new prmtop file (without waters) before
proceeding with the cross-correlation analysis. Also, when you strip waters,
you generally want to use the "nobox" option on the trajout command. But
I'm just guessing here about things that may have gone wrong.
Without knowing a lot more about what you actually did, it's hard to be of
much help.
