Figure 2.

Normal probability plots of z-transformed correlation coefficients. For normally distributed variables, the data points lie approximately on the identity line. The insets show central slices through representative densities used to calculate the underlying correlation coefficients. The noise parameters used to generate the maps are listed in Table 2 ▶. (a) Maps were calculated at 6 Å resolution from PDB entry 1oao chain C. (b) Maps were calculated at 15 Å resolution from PDB entry 1lfh. (c) Maps were calculated at 12 Å resolution from PDB entry 1blb. (d) Maps were calculated at 20 Å resolution from PDB entry 1hwz.
