Having difficulty with how to use label2label for this purpose. Just need a binary mask of medial wall (vertex number and 0 or 1s) on native surface. What's would this command be?

    Do you mean you want a binary mask of the medial wall?
    You can create a mask of the cortical label (?h.cortex.label) with
    mri_label2label
    You can then invert that with something like
    fscalc lh.cortex.mask.mgz not -o lh.medialwall.mask.mgz

        Is there a freesurfer file that contains metric info that
        delineates the medial wall in the native surface output for an
        individual?

        It appears to be associated with the ?lh.aparc.annot file (below).

        I’d like to be able to export the medial wall metric into
        Worbench.

        Thanks.
