Hi all,

when the following leap script (AmberTools 1.2) is executed and followed by, the .top file is suitable for TIP3P and the .gro is suitable for
TIP4PEW. The .top file knows nothing about EPW. Gromacs then remarks that
the nunber of atoms in the .top and .gro don't match. Is there something
amiss in the leap file? There are no waters in chp16.pdb .
