Dear freesurfer experts,

I have a pretty naive question but would like to confirm.

When we use --3spaces option in multiple comparison correction, does that mean we set the Cluster-wise threshold (cwp, not Cluster Defining Threshold or Cluster Forming Threshold) to 0.5/3=0.0167 for lh. Similar cwp at 0.0167 for rh and subcortical?

In addition, if we use "--cortex" to restrict the calculation on cortex only, where can we find the corresponding mask or label file for cortex?

Thanks,

Chao-Gan
