¥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:
3dclust -1thresh 300 1 200 Ôfunc_fred+tlrc[2]Õ
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:
