WebThe reset_mol_ids keyword invokes the reset_atoms mol command after a reaction occurs, to ensure that molecule IDs are consistent with the new bond topology. The group-ID used for reset_atoms mol is the group-ID for this fix. Resetting molecule IDs is necessarily a global operation, so it can be slow for very large systems.
