RW is distance-dependent atomic potential for protein structure modeling
and structure decoy recognition. It was derived
from 1,383 high-resolution PDB structures using
an ideal random-walk chain as the reference state.
The RW potential has been extensively optimized and tested on
a variety of protein structure decoy sets and demonstrates a significant
power in protein structure recognition and a strong correlation with
the RMSD of decoys to the native structures.
