Select an Input Volume\n2. Place Source Seeds or select an existing Fiducial List (after selecting a Fiducial List in the Source Seeds selector, it becomes set as the active Fiducial List automatically)\n3. Optional: Place Target Seeds or select an existing Fiducial List (if Source Seeds and Target Seeds point to the same Fiducial List, Target Seeds will be ignored.) If you want to ignore sidebranches, target seeds are required!\n4. Optional: Select an Output Volume for the Initialization stage\n5. Optional: Select an Output Volume for the Evolution stage\n6. Optional: Switch between Volume Rendering or Marching Cubes as 3D Output\n7. Select an Initialization Threshold (the slice viewers show feedback)\n8. Press Start and the initial surface is overlayed in the slice viewers as a label map and shown in the 3D window\n9. Configure the behaviour of the evolving surface by using the three weight sliders\n10. Optional: Enter the number of evolution iterations\n11. Press Start and the evolved surface is overlayed in the slice viewers as a label map and shown in the 3D window\n\nwith Parameter Sets:\nPresets set the Threshold for Initialization and the Weight Sliders for Evolution. Some presets for different Use Cases exist and can be selected.\n\nEvolution functionality only:\nIf an existing segmentation (must be a binary image) should just be evolved using the Evolution stage, set the Initialization Output Volume to the existing segmentation and proceed to the Evolution Stage. The Initialization Output Volume is the input for the Evolution stage."
