Thanks a lot  
First, i tried to follow the tutorial but i cannot find the video tutorial at all…  
([New video tutorial for Segment editor - lumbar spine segmentation for 3D printing](https://discourse.slicer.org/t/new-video-tutorial-for-segment-editor-lumbar-spine-segmentation-for-3d-printing/700))

So I was going to refer to a few youtube. But the bar setting of threshold range is not active. I’m curious about the reason why it is not active…
