I want to perform MD on RT ionic liquids using an amber force field. I have generated mol2, frcmod files. Then, I loaded my complex.pdb, which contained dmc and TTE (generated using Packmol).when I tried to run this command (> saveAmberParm ionicbox complex.prmtop complex.inpcrd)then I encountered this error:
FATAL: Atom .R.A does not have a type.
FATAL: Atom .R.A does not have a type.
