There's no way to know that, but hopefully so. The charges from ATB would
appear to me to be somewhat over-fitted, so adjusting them would be the first
place I would look. Introducing new atom types means you have to make sure a
lot more interactions are reasonable. Simple charge adjustments using existing
atom types is straightforward, but it may be possible that you need to do more work.
