Percent label agreements and type II errors (II) are given for each number of atlases (A) used to label subject group 1, group 2, and all subjects. The accompanying graph is in Figure 6. Standard deviations are in parentheses (for type II errors, σ equals 0.02 for all subjects and 0.01 for groups 1 and 2).
