Hi Bruce,  I would like to convert the .mgz label volume to a surface label for that subject, but mri_vol2surf requires a registration file.

  you don't need to register it if it's shown properly in tkmedit
  or freeview. Can you tell us more about what you are trying to
  do?

        Hi Bruce, 
        Thanks for the quick response. The label is a
        manually traced area of the
        cortex. It is in subject scanner space and has a
        single value, so it
        probably would not work with bbregister. I can load
        it in tkmedit as a
        segmentation and the alignment is correct. I
        attached a screenshot. Is there
        a way to select the values greater than zero in
        tkmedit and save as a label
        that could be used in vol2surf? I have other labels
        that are larger so I
        would prefer not to retrace them if possible.

              what is the label? What space is it in? If it
        has gray/white
              contrast you could try bbregister.

                    Hi Freesurfer Experts, 
                    I have a binary volume label in subject
        space that I
                    converted from MINC to MGZ. I would like
        to register
                    it to
                    the surface of that subject as a flat
        label. I
                    thought I would be able to do so with
        mri_vol2surf
                    but I am not
                    sure how to generate the required
        registration file.
                    Is that the correct command, and if so,
        which
                    registration
                    file should I use?

                    Thanks
                    Jonathan
