Because the current protein mapping scheme in Martini 3 (v3.0.0) uses regular-sized beads (4-1 mapping) in the backbone, 1 forward mapping of atomistic proteins often leads to a substantial overlap of the backbone LJ spheres resulting in repulsive interactions, especially in secondary structures where the backbone is tightly packed. These non-bonded interactions are excluded when using both elastic networks and the GoMARTINI model, which is a contributing factor to the stabilization of these models. We also find that non-bonded exclusions are needed between backbone beads. However, since exclusions cannot be defined intermolecularly in GROMACS we do not use exclusions in the tertiary network for consistency with quaternary networks. This means that the OLIVES interaction energy in the tertiary network is added on top of the non-bonded interactions present in the Martini 3 interaction matrix. Because the non-bonded interactions are excluded from the secondary network, we add the non-bonded energy back onto the energy of the OLIVES bond. The resulting secondary and tertiary network pairings are then collected and used to create LJ pairs with
