Module Description

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

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
