Initial test with the "Ridge detection function".  Dark and Bright ridges are detected separately. In this example, only initial pre-processing for Dark ridges is shown.

"Invert Volume function" - extended function from ROI only, to include SI-volumes and Real volumes.  Moved the corresponding User Interface item to "Main Menu>Volume".

Corrected an "initialized memory" error in all Liver DCDI model variants.  It was leading to "Unsupported color mapping" error message.
