Module Description

Allows the user to modify the display of diffusion tractography. Examples are: change of color, display of the fractional anisotropy along the tract, display of the tracts as tubes or lines, interactive selection of the tracts, and cropping.

Use Cases

Most frequently used for these scenarios:

  • Use Case 1: Change the scalar quantity displayed along the tract, like Fractional Anisotropy or Color By Orientation
  • Use Case 2: Display the tracts as lines or tubes
  • Use Case 3: Interactive selection or cropping of a certain bundle.

Panels and their use


  • Simple Display
    • Solid Tube Color: Display the tracts as tubes in solid color, if checked
    • Lines: Display the tracts as lines
    • Tubes: Display the tracts as tubes
    • Tubes Slice: Show the tracts in the 2D view (Tubes Slice)
    • Glyphs: Display glyphs representing the diffusion tensors along the tracts
    • Tubes: Specify the solid tube color
    • Percentage of Fibers Shown: Select how many of the total tracts in the bundle are shown. Useful for performance.
  • Fiber Bundle Selection: Perform selection and cropping of the tracts
    • ROI for Fiber Selection: Select a ROI to use as an interactor with the tracts
    • Disable/Positive/Negative ROI: Set the selection mode to Select everything, Select the tracts traversing the ROI or Select the tracts not traversing the ROI
    • Interactive ROI: Allow the fiber selection and cropping in an interactive way
    • ROI Visibility: Display the ROI
    • Extract Bundle From ROI: Extract a new fiber bundle which contains only the selected ones
    • Update Bundle From ROI: Update the current fiber bundle leaving only the selected ones
      • Confirm update: Confirm update given the ROI
    • Enable Interactive Edit: Allow to edit the ROI in an interactive way
  • Advanced Display: For the lines, tubes and glyphs
    • Visibility: Toggle the visibility of the bundle
    • Opacity: Change the transparency level of the bundle
    • Fiber Bundle Coloring: Change the way the bundle is colored, one of "Of Tensor Property", "Of Scalar Value", "Color Fibers By Mean Orientation", "Color Fibers By Segment Orientation", "Of Fiber Cluster Group ID" or "Solid Color".
      • Auto W/L: Adjust the window level automatically
    • Material Properties: Adjust Color, Opacity, Ambient, Diffuse, Specular, Power and Backface Culling of the displayed tracts.
      • Preview: Color preview given the adjusted properties
      • Presents: Select one of the predefined property sets
