Volume View
     Volume View displays brain volume slices. In
      Volume View the Toolbar looks like this:
    
     
     
    
      - Slice
            Plane contains buttons to set which volume slice planes
          are displayed: P (parasagittal), C (coronal),
          A (axial), All (all 3 planes).  
 
    
    
      
    
    
      
        - The Reset button resets the
            orientation/zoom to the default.
    
      
        - Custom
                  Orientation allows one to set and save (or
            not) a specific transform (pan, rotate, oblique rotate,
            zoom) for a surface or volume.
    
      - Montage contains settings for
          viewing multiple volume slices from a single slice plane at
          once. Rows/Cols set the number of Rows or
          Columns of slices to display. Step sets the index
          spacing between slices in the volume slice montage.  
 
    
      
        - Slice Indices/Coords
          contains
              settings for the slice index and stereotaxic (Talairach)
              coordinate to be viewed for each slice plane. 
          
        
          - The vertical Origin button
              rests the slice indices to the default (centered at the
              AC). 
    
     
      
         
        - The  button (default on)
              activates movement of the crosshairs/volume slice to the same
              plane as the brainordinate selected in any of the Viewing
              Tabs in the same yoking group as the Volume tab. button (default on)
              activates movement of the crosshairs/volume slice to the same
              plane as the brainordinate selected in any of the Viewing
              Tabs in the same yoking group as the Volume tab.
    
      
        - The pull-down at the bottom toggles
            between Orthogonal and Oblique volume
            viewing. 
    
    
      
    
    
    
      - Clipping
          contains settings for cutting down Surface, Volume, or
          Features data to be viewed.
      -  Tab
          contains cross-tab functions for yoking the display of two or
          more Viewing Tabs.
