[Freesurfer] mc-z, the same CWP for all clusters?

Hi all,

I did the correction for multiple comparisons using mc-z with 10000 iterations (sign=abs, Threshold=1.3). Now for all the clusters (30 clusters) on one of the hemispheres I find the same CWP (0.00140), CWPLow (0.00090) and CWPHi(0.00190) for all of them. For the other hemisphere however there is only one cluster with CWP of 0.01940 and all the other clusters (34 clusters) again have the same values for CWP (0.67740) , CWPLow(0.67140) and CWPHi (0.68340).

Is this normal?!!

I have 2 groups with 10 subjects in each group. I was thinking maybe I should just increase the number of iterations...

I appreciate your comments on this.

Thanks, Nasim
