Description:randomise -i -o -d -t [options] randomise produces a test statistic image (e.g., ADvsNC_tstat1, if your chosen output rootname is ADvsNC) and sets of P-value images (stored as 1-P for more convenient visualization, as bigger is then "better"). The table below shows the filename suffices for each of the different test statistics available. Voxel-wise uncorrected P-values are generally only useful when a single voxel is selected a priori (i.e., you don't need to worry about multiple comparisons across voxels). The significance of suprathreshold clusters (defined by the cluster-forming threshold) can be assessed either by cluster size or cluster mass. Size is just cluster extent measured in voxels. Mass is the sum of all statistic values within the cluster. Cluster mass has been reported to be more sensitive than cluster size (Bullmore et al, 1999; Hayasaka & Nichols, 2003).
