I did have both: SET HETATM_IO = on, WATER_IO = on However, the water coordinates were generated and also my heme hetatm had generated coordinates. The SO4s were the only ones that didn't work. This is why I am thinking it has something to do with the settings in restyp.lib. Any other ideas? Cheri

SET HETATM_IO=on

This allows the 'HETATM' groups to be written to the model file.
