Slicer version: 5.6.2

Hi,  
I am trying to run the code of the script repository: [Script repository — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#resample-segmentation-to-higher-resolution)

However, I get: NameError: name ‘segmentationGeometryLogic’ is not defined.

And if I add, segmentationGeometryLogic = slicer.vtkSlicerSegmentationGeometryLogic()

AttributeError: ‘vtkSlicerSegmentationsModuleLogicPython.vtkSlicerS’ object has no attribute ‘SetReferenceImageGeometryInSegmentationNode’

Any help would be greatly appreciated!  
Thanks,  
Maria

I just tripped over this too. The example is clearly missing some code.

Did you find a solution that works? If so, can you share it? I’m looking to try this…

Thanks!!!

Found this, which might be helpful. Haven’t tried it yet, YMMV:

> @lassoan Thanks for your help again! The source code of vtkSlicerSegmentationGeometryLogic::ResampleLabelmapsInSegmentationNode is really helpful, and I finally completed this function correctly based on the source code. The issues aren’t technical issues, and since it works right now, there’s no needs to worry about upgrading. For those who are interested, here is my code. segmentIDs = vtk.vtkStringArray() segmentationNode.GetSegmentation().GetSegmentIDs(segmentIDs) #Create desired geometry…

It would be great if someone could submit a PR to fix the script.

Wish I were less of a “script kiddie in 3D Slicer land”, that’d be fun.

This should do it
