Hi freesurfers,
According to the page on group analysis(http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis), the cluster summary contains ALL clusters, regardless of their significance. However, a paracentral cluster (see figure attached) had a uncorrected p value of 10^-6 but doesn't show up in mz-c.sig.cluster.summary even after I lowered the cwpvalthresh to 0.1 in a cwp simulation.  

Any advice or suggestions would be greatly appreciated.

Many thanks,
Martina
