Dear all,
I have some questions about the outputs of mri_glmfit-sim (which I used to perform permutation tests on my surface analyses). When I compare *.sig.clusters.mgh and *.sig.masked.mgh surfaces, I notice that the clusters reported as statistically significant also include some vertices that are slightly below the cluster-forming threshold (especially at the borders of the clusters). It would appear as if some spatial smoothing has occurred on the clusters themselves. Why is it so? Is there a way to perform clustering on the data that are above cluster-forming threshold? Thanks, Marco _____________________ Marco L.
