Figure 3.

Z-Scores (inset) measure the energetic difference of near-native conformations to the average energy of the decoy set in units of its standard deviation. The vertical axis arranges the ROSETTA decoy sets in order of increasing size. The upper-horizontal axis gives the bRMSD of the lowest energy decoy to native for the lowest energy decoy in the decoy set; obviously this approach can select only among the decoys in the database. The lower-half of the main figure shows the Z-scores of the native ensemble for decoy sets (more negative is better).
