Distinguish two ROIs with same Name but different Number. #110

Dear all, i have a problem that i'm not able to solve by myself.

I want to import a RT Structure containing 2 different ROI with the same (3006,0026)ROIName = "Lesion01" but with a different (3006,0022)ROINumber = {1, 2}.

When I import it I'm no more able to distinguish them, neither in the Data nor in the Segmentation module. The Name is the same, the Number is not reported at all.

I've tried to understand if the first one always has ROINumber = 1 whereas the second one is the ROINumber=2 but I can't find the block of code.

Can someone help me to distinguish the two segments? Thank you!!

Interesting problem indeed.

What I'd do is I'd set the ROINumber as a tag to the segment. Then if you hover the segment in the Data module then the ROINumber will be included in the tooltip.

It's only one line of code. I can do it for you today or tomorrow if you'd like.

It's my first approach to Slicer and Python, but I've already coded in C++ or vb. Indeed I was looking for a way to concatenate ROINumber + "-" + ROIName in the segmentation name, but maybe the tag is a smarter way.

I'd really appreciate your help, maybe I'll also learn hot to use Slicer! Best.

I implemented the change, it is supposed to be available in tomorrow's Slicer preview version. It was more than a line of code doing it right, but it took only a few minutes :)

This is how the ROI number appears:

I hope this is fine.

Thank you master. Tomorrow I'll let you know if it works!

Best

Works like a charm!!

Thank you boss!
