Hello,
Continue on this topic, I found that the charge group in the converted
Gromacs topology file is totally messed up.
Some charge groups contain several residues, I guess that charge groups
are not defined in the psf file. How could this happen? Could some one
give a clue? Thanks a lot!
All the best,
Qinghua
