Gromacs invalid order for directive atomtypes
WebShort answer: if your ligand introduces new [atomtypes], it must be #included before any [moleculetype] appears. That's why it works for a cofactor-in-water system; the cofactor is the first [moleculetype]. So, if I understand it well, grompp reads the directive [atomtypes] of cofactor.itp, then the [moleculetype] of the cofactor, then the rest ... WebJan 7, 2014 · The [atomtypes] directive is at the force field level, so any new [atomtypes] need to be declared before any [moleculetypes] appear in the topology. See Chapter 5 for the required hierarchy.
