When you say that NAMD requires "bond, angle and dihedral information"
you mean that you need NAMD requires de topology, isn't it? In
principle if you want to simulate a system containing 1000 water
molecules, you'll need only the bond and angle information. You can
easily get the topology (as a pdb file) and parameters (all the rest)
by using psfgen, which is included in both NAMD and VMD. You don't
need to do this by hand. If I didn't understand you well, pls make me
know :)
