Hi Justin,

I merge two molecules as a single molecule type. Now I'm trying to do
energy minimization of the system, getting errors like

Fatal error: [file topol.top, line 55130]:
   No default Proper Dih. types

Any idea for this type of errors.


The force field does not have parameters for whatever dihedral is listed on line 55130 in the topology.
