[Freesurfer] Using aseg to sample other image types

Dear Freesurfer,

I have co-registered a map of whole brain T2-relaxation time values to the corresponding aseg.mgz for this subject (see attached jpegs). Does a tool exist in freesurfer to enable regional sampling of T2 values from the T2-relaxation time map based on aseg?

Thanks for any thoughts.

Happy New Year.
