That threshold is on the actual voxel values. For example,
it might be based on the t-stat for an uncorrected p-value,
while 40 is the voxel count and 1 is the radius.
What does test.nii contain? And forgetting any example,
exactly how do you want to threshold and cluster the data?
The specific questions are what uncorrected z-value threshold
and what minimum cluster size do you want to apply? Exactly
what cluster limits do you want to impose?
