Hi,

I have a volume that contains only values that are listed in my custom LUT (~70 different values representing anatomical structures):  
Example:

 ![image%20(2)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/e/1/e1c71782041056bfa80df6a3a66d20b7bfea86d1.png)  
I want to automatically create a labelmap, that would assign the values of the volume to the corresponding values of the LUT. Therefore I would be able to visualize the structures with their assigned colors, modify them or for example create a 3D model of all the structures. If I was to do this by hand I would have to manually apply thresholds and create a label map for each structure individually and of course I don’t want to do that. Is it possible?  
Thanks in advance!

In Volumes module, convert the volume to labelmap and select your custom LUT. If you import this labelmap to a segmentation node (using Segmentations module) then colors and segment names should be automatically set based on your LUT.

You can create a custom color table as describe here: [https://www.slicer.org/wiki/Documentation/4.8/Modules/Colors](https://www.slicer.org/wiki/Documentation/4.8/Modules/Colors)
