• If you want to associate trees with a specific color channel, select a single channel using either the Channel panel on the left side of the 3D environment window or the Image Adjustment tool (on the Image and Workspace ribbons) in the 2D window.

• To trace, click along a vessel, then right-click to end.

• Snap cursor to tree: Check the box to enable this feature, which:

  • Corrects for lack of precision with mouse clicks.

  • Enables closing a loop while tracing.

  • Lets you resume tracing from an ending by clicking the ending.

• Cycle tree colors: A new color is used every time you start a new tree.

• Pan to window after each click: Each point you click that falls outside the field of view is re-centered automatically.

• Display other trees as centerline: Displays trees that are already traced as lines (instead of showing thickness).
