To determine the best combination of parameters for the ScSc term, a set of 30 proteins was remodelled using the ScSc term only with different atom sets, bin sizes, and with or without histogram smoothing. The side chain RMSD was calculated for side chains atoms excluding Cβ atoms. Results for both the reduced and full rotamer libraries are presented.
