Do you want a binary map? If so, you can run
mri_binarize --i aparc+aseg.mgz --o pfc.mgz --match Id1 Id2 ...
where Id1 ... is a list of segments you want in your binary map as found in $FREESURFER/FreeSurferColorLUT.txt, eg, 1028 is left superior frontal

1028 ctx-lh-superiorfrontal 20 220 160 0

Does anyone know how to extract the Prefrontal cortex region from the wmparc.mgz or aparc+aseg.mgz?

Thanks,

Satya.
