Hi all,  
I have a CT with a dose cube and I can import and visualize them in Slicer (v.4.10).

At this point would like to show also a colorbar for the dose.

Do you have any suggestion?

Thank you very much.  
Paolo

Go to the Isodose module and use the checkboxes on the bottom. You _don’t_ actually need to calculate an isodose for showing the scalar bars, just check the boxes.

Thanks a lot @cpinter!  
I thought I had to compute isodose first.

No, you do NOT have to calculate isodose. Just the checkbox, that’s all
