• Much of the header has been removed for clarity
• Size(n) - number of voxels in cluster
• Size(mm3) - size of cluster in millimeters cubed
• MNIX, MNIY, MNIZ - MNI305 Coordinates of the maximum
• Max = maximum voxel-wise signifiance in the cluster
• GRRFCWP - p-value of the cluster (CWP=Cluster-Wise P-value)
• Last column is the approximate segmentation ID
