Borders
     The Borders Tab in the Features Toolbox
      contains options for display and selection of loaded and newly
      created borders on brain surfaces.  
    
      -  Display Borders toggles border
          display on and off. When Border Mode
          is turned on, Display Borders is turned on by default.
      -  Group: identifies the Border
          group for the Active Tab. Tabs assigned to the same Group will
          display the same borders with the same attributes. 
      - Borders Attributes contains
          options for viewing borders.
      
        - Contralateral check box toggles
            on display of borders that are currently being displayed on
            one hemisphere to be displayed on the contralateral
            hemisphere (on top of that hemisphere's own displayed
            borders, if any).
 
      
        - Draw As sets the shape of the
            border components (Lines, Spheres, Squares, Spheres and
            Lines).
 
      
        - Coloring sets the Class, Name, or Standard Color
            as the border color source.
 
      
        - Standard ColorSelects the color when Coloring is set to Standard Color.
 
      
        - Line Diameter controls the
            border thickness if line is selected as the border
            component.
 
      
        - Symbol Diameter controls the
            size of the sphere or square symbol border components.
 
      
        - Unstretched Lines is used
            to correctly display a border from a 3D surface on a flat
            surface when the border crosses a surface cut from
            flattening. The distance indicates the limit for how much a
            border can be stretched across a cut surface before it is
            NOT displayed. Specifically, if the value of [(length of
            border on flat surface) / (length of border of 3d
            volume-interaction surface)] exceeds the Unstretched Lines
            value then the border is NOT displayed.
 
      
 
     
    
      - Borders Selection controls group
          and individual display selection for borders. If a higher
          level group is selected on or off, all borders below that
          level will be similarly selected on/off. The All On/Off
          buttons allow for quick toggling of all borders on or off.
