¥The program 3dclust looks for clusters of activity that fit the criteria set on the command line, and prints out a report about the active voxels that make up the ROI cluster(s)

¥Example:
å3dclust  -1thresh 300  1 200 Ôfunc_fred+tlrc[2]Õ
å
HThe above command tells 3dclust to find potential cluster volumes for dataset func_fred+tlrc, sub-brick #2, where the threshold has been set to 300 (i.e., ignore voxels with an activation threshold <300).  Voxels must be no more than 1mm apart, and cluster volume must be at least 200 micro-liters in size.

HOnce these ROI clusters have been identified, a report will be printed out:
