Displays cluster centroid (-, -, and - MNI coordinates), maximum -statistic within the cluster, value (unadjusted) of the maximum -statistic, cluster size in number of contiguous voxels, and permutation test-based cluster value. The cluster -value compares the size of each suprathreshold cluster to the permutation distribution of the largest cluster, thereby accounting for multiple comparisons. Only results from clusters of 100+ voxels shown.
