Do you mean cluster-wise threshold or cluster-forming threshold?

Dear Freesurfer Mailing list,

While running a glm anlaysis with monte carlo correction (using 
cluster wise thresholds of .05 & .01), I encountered the following issue:
When examining the clusters formed for each of the different cluster 
wise thresholds, the .05 threshold resulted in a superior temporal 
cluster, while the .01 threshold resulted in a two lateral occipital 
clusters that did not overlap with the cluster from the .05 threshold.

Do you know why there would be no overlap between significant regions 
at different cluster wise thresholds? I was aware that a cluster which 
is significant at .05 may split or be smaller at .01, but I do not 
know why entirely different regions would be significant.
