Hello all,
I have a system containing heme, I build the fragment file and segment file for heme and another ligand that I'm gonna put into QM region. Then I set up the QM/MM optimization, however, NWCHEM kept looking for atom C in WAT.sgm, where WAT is standard water. Any suggestions?
Atom C not found in segment ./WAT.sgm
