Dear All, I want to calculate the interaction energy between water and protein backbone. However, in mdp file, when I am using
energygrps = SOL backbone grompp is returning the following error. Fatal error: atoms 1 and 2 in charge group 1 of molecule type 'Protein_chain_A' are in different energy groups Can someone kindly point out my mistake?
