[gmx-users] [ implicit_genborn_params ] for Gromos54a7 FF

Dear all.
I wonder where the [ implicit_genborn_params ] section should come in the
below topol.top file for which the Gromos54a7 force fields are used?

For the Amber and OPLS-FF I notice that all the [ implicit_genborn_params ]
parameters are in a gbsa.itp file but that was not the case for Gromos54a7
and even it did not worked when I created a gbsa.itp for for gromos5a7.

#include "/u/alex/.local/gromos54a7.ff/forcefield.itp"
#include "A.itp"
#include "B.itp"
#include "C.itp"
[ system ]
A-B-C in implicit water

[ molecules ]
A               1
B               29
C               14
B               29
C               14

Thank you
