 * 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
