[gmx-users] Atom Types in ffbonded.itp

[Lara Bunte]

Hello

I want to write my parameters in the ffbonded.itp file in the CHARMM27 force field folder. I wrote my atom types in this file. This atom types are defined by me in atomtypes.dat

grompp gives me an error 

Fatal error:
Unknown bond_atomtype

for all my atom types. Do I have to declare that atom types somewhere else than in atomtypes.dat?


What is the problem?

Greetings
Lara
