¥ The result:
HThis example thresholds the dataset on subrick #2 (Ôfunc_fred+tlrc[2]Õ) at F-value 300 (-1thresh 300)
HClusters together all the surviving nonzero voxels using
a contiguity test of 1mm and keeping only
clusters at least 200 mm3 in volume (-1clustorder 1 200)
HAll voxels in the largest cluster are assigned value 1
(say, 1200 voxels in one cluster), the second
largest are assigned value 2 (say, 920 voxels in one cluster), etc., and the result is written to disk in
dataset clust_roi+tlrc
