Generally, you do not smooth it as averaging over the ROI is effectively a type of smoothing. If you were to smooth prior to the averaging, you'd get one area smearing into another.

External Email - Use Caution
Dear Freesurfer Experts,
I am wondering whether the extracted ROI volume data acquired when using the command aparcstats2table needs to be smoothed? I performed surface smoothing using surf2surf for cortical thickness data, but cannot find a way to smooth the volume data listed in aparcstats2table. Is it recommended that I do not perform smoothing?
Thank You,
Ryan
