[gmx-users] grompp Unkown bond_atomtype C2

[Lara Bunte]

Hi 


in my .rtp file I wrote in the [ atoms ] block

C2   CN1A    0.7481   1 


but in the atomtypes.atp file I wrote

CN1A    12.01100


So I declared it. So what do you mean with "such an atom type doesn't exist"?

Greetings
Lara

You're making use of an atom type called "C2" in some bonded interaction, but 
such an atom type doesn't exist.  You need to define it.
