Hi Steve,
Originally we wanted to get a minimum cluster size as a kind of threshold for the feat group level zstat images (obtained from group comparisons based on seed voxel analyses on resting state fMRI) as the thresh_zstat images appear quite stringently thresholded - that's why 3dcluster appears attractive (I hope that's a sound reasoning, I am not a statistician...)
Randomise won't give a minimum cluster size (although the TFCE clusters have been tested against a critical cluster size as far as I understand, can I actually fetch this critical size from somewhere?), though the output will be corrected.
So taking the copes is fine?
Thanks!
Torsten
