TIP4P water can be used with the CVS version of namd; I'll send you
instructions off list. While it seems to be working properly I'm keeping
it labeled experimental until we get final approval from Prof. Jeffry
Madura, who volunteered to do some testing (and is rather familiar with
the model). In the meantime, I'm not responsible if a dingo eats your
research because you used it.
