Vol/Surf Outline
        The Volume Surface
        Outline tab (Vol/Surf Outline for short) in the Overlay Toolbox
      allows one to set parameters for viewing brain surface
      outlines on volume slices in the Volume or All (Whole Brain) Viewing
            Tabs (inactive in all other Views).  
      
      This is useful for comparing Freesurfer, or otherwise
      reconstructed, surfaces with volume slices, as a check of the
      quality of the surface.  It is also useful for viewing
      Connectivity data (dense connectivity and BOLD dense data series
      files) on both the cortical ribbon and in subcortical voxels. 
    
      - On checkbox toggles on/off a brain surface outlined
            on a volume slice view.
      - Color Source sets the coloring of
          the outline as provided by either (A) the displayed overlays
          from another Tab, or (B) from a list of default solid colors.
      - Thickness sets the width of the
          lines.
      - File selects which surface will be
          used for the outline display.
