Re: [Freesurfer] the unknown zone in the average

Hi Xin,

you can use mris_anatomical_stats with -l ?h.cortex.label, which should be generated automatically, to avoid noncortical regions.

Hello, Group,

We calculate the globe mean of thickness by using mris_convert -c lh.thickness lh.white lh.thickness.asc mris_convert -c rh.thickness rh.white rh.thickness.asc and then merge two .asc files to calculate the average

Does this procedure include the neocortex only, or also include some spots in the unknown zone that also have readings in the thickness map?

If the unknown zones are included how to exclude them?

we processed the data with the version prior to 4.0.1.

Thank you in advance,
