Sorry made a mistake: it is CFT= 4

freeview -f $SUBJECTS_DIR/fsaverage/surf/rh.inflated:overlay=cache.th40.pos.sig.cluster.mgh

Thank you

Subject: Re: [Freesurfer] Clusterwise Correction for Multiple Comparisons

Can you send your full mri_glmfit-sim command line? It looks like you used a cluster forming threshold (CFT) of 1.3. If so, when you look at the uncorrected sig.mgh files and threshold at 1.3, do you see the same thing? Also, what is the threshold for the image below

Hi,

After running mri_glmfit-sim (two classes) and 

freeview -f $SUBJECTS_DIR/fsaverage/surf/rh.inflated:overlay=cache.th13.pos.sig.cluster.mgh

I get this: 

I would like to know if this due to an error (do I need to change threshold) or no significant clusters.

Thank you,

best

Akia
