Legacy color maps from Slicer2 include Grey, Iron, Rainbow, etc. Those color maps with "labels" in their names are usually discrete and don't work well for the continuous scalar overlay ranges.

Module Description

This module is used for loading, saving, and changing the appearance of DTI fiber tracts.

Usage

Load

  • Load Tractography allows the user to load a single track file. The file should be a VTK polydata file (.vtk or .vtp) containing polylines with Tensor point data.
  • Load Tractography directory will load all the VTK models (*.vtk) that are located in in the selected directory

Display

  • Fiber Bundle Select: Select the bundle that you want to modify from a list
  • Display for Lines/Tubes/Glyphs: select which representation to edit. Note that you can have more than one representation visible at the same time, for example Lines and Glyphs.
  • Visibility: Turn a fiber bundle on or off in the 3D window
  • Color By Scalar: Select from the list of derived tensor scalar properties such as Fractional Anisotropy, etc.
  • Scalar Color Map:Sselect the color mapping used to map from the scalar values to colors.
  • Clipping: Set clipping on or off for this bundle. Once it is on, go to the Models->Clipping pane to set the options.
  • Opacity: Set how transparent this track is.
  • Set Color: Set the base color for this bundle.
  • Glyph Display Properties: Only applicable to glyphs.
    • Glyph Type: Lines, Tubes, or Ellipsoids.
    • Scale factor: Controls glyph size.
    • Spacing: Controls the number of glyphs along the tract.

Save

  • Fiber Bundle To Save: Select a bundle from the list.
  • Save Tractography: Opens a file browser to let you select the location to which to save the file. The valid extensions and file types that can be used are:
    • .vtk poly data
    • .vtp xml poly data
