Figure 6

Illustration of spatial variability between subjects causing informative clusters to be missed at the group level. a. Half of the subjects have the cluster of informative voxels (yellow) on the left side of the ROI while the other half have the cluster on the right side; all cluster voxels are required for significant classification. The searchlight (red circle) is large enough to encompass the informative voxels, but neither appears significant in the group information map. b. Information maps for each subject group (green) do not overlap despite overlapping informative clusters (yellow).
