[Freesurfer] Run stats for both hemisphere?

Dear freesurfer experts,

I am wring to ask a stupid question, which I did not find the answer in the mailing list.

I am going to run stats on the thickness data as described in the tutorial, do I have to run separately for each hemisphere? If I am not wrong, we have to specify the hemi in the data assembling stage. Are we able to run once for both hemis in the glm and correction stage?

If not, I am a little confused in the correction stage, which we specify the --2spaces in the simulation. As indicated in the tutorial, this is for adjusting p for both hemis.

Another question is about subcortical areas. Do we have to run stats for the cortical and subcortical areas separately?

Thanks
