Those lines are related to DMPC lipid dihedrals.


I know that much. I am trying to extract some actual detail here so I can help you reach a conclusion. The error indicates line numbers in the topology. On those line numbers are a sequence of atom numbers, which can be mapped back to atom types. I'm asking you what that specific information is.

Hi Justin,

Should I use R-B dihedrals for DMPC lipids rather  than periodic
dihedrals.


You should use whatever the force field tells you.


  I'm getting an Error message like,

ERROR 18815 [file topol.top, line 54180]:
    No default Ryckaert-Bell. types


ERROR 18816 [file topol.top, line 54181]:
    No default Ryckaert-Bell. types


What are the dihedrals on these lines?
