• DWI Gradient Editor
  • Will be described by Kerstin
• Glyph On Slices Display editor
  • Controls the tensor glyphs visibility on individual slices in both 3D and 2D viewers.
  • Selects the scalar to color the glyphs by and the color map to apply.
  • Controls glyphs opacity, glyph type, scale and sampling rate.
