Dear Freesurfer experts, I have a question regarding tk surfer. If I load the cache.h13.abs.sig.cluster.mgh file, I'll only see the clusters surviving the statistical threshold I set, don't I? (e.g. I set the cluster finding threshold at 0.05 (Monte carlo simulation), keeping all clusters with p<0.001, which gives me for example one cluster; it's only this cluster that will be visualized, right?) I ask this because sometimes only a few clusters are kept, but I see a lot of the brain coloured in tk surfer, presumably because the clusters are very large. Thanks, Maaike
Yes, if you set the clusterwise threshold to 0.05, you will only see clusters that or more significant.
