Creating a New Root

To create a root, use the following steps:

      1. Click the Annotate button if you haven't already to allow the editing of roots.
      2. Select the New Root button , Edit > New Root, or Ctrl + R.
      3. Press and release the left mouse button within the image window at the end of a root to make the first point. 
      4. Move the mouse along the root, creating more points as needed using the method in step 2.  More points are necessary to allow  the root drawing to follow curvatures in the root.
      5. When all the root points have been drawn, press and release the left mouse button twice (double-click).
      6. A circle graphic which represents the diameter will appear on the root.  Move the mouse cursor along the root to move the diameter until the desired diameter-drawing area has been reached. 
      7. Press and release the left mouse button to drop the diameter at this point.
      8. The diameter length can now be set.  Move the mouse cursor away from the root to increase the diameter length; move the cursor closer to the root to decrease its length.
      9. Once the desired diameter is achieved, press and release the left mouse button to finish the root drawing.
