Hello everyone,

I'm trying to compute the activation free energy (using FEP in Gibbs module)
of a proton transfer reaction of an enzyme.

I have tried to load the reactant of the reaction (state 0) and the
Transition State of the reaction (state 0) in leap. I also modified the
charges and parameters for the state 0. But when I tried to save the parm
and coord files of the perturbed state 1(saveAmberParmPert), leap complained
that I was missing some bonds, angles and dihedral parameters concerned with
dummy atoms.

Can anyone tell me how to create the dummy atoms parameters in order to
do this?

Many thanks
