Supplementary Figure 3: Identification of model errors using the local density correlation.

For each refined model of 20S, local correlation between each residue and the testing map is calculated. The fraction of residues deviate more than 1Å (black) or 2Å (green) from the reference model (y-axis) is plotted for each local correlation bin (x-axis) at (A) 3.3, (B) 4.1, (C) 4.4, and (D) 6.0Å resolutions.
