Problems with path

[weemscreekstudios]

I am trying to use the Cervical Vertebra Tools extension on 5.03 r30893/7ea0f43 and am getting a “setup local paths variables” error. Searching has not found a good link.

Ubuntu 20.04

I get the following errors:

VisSimCommonLogic: initializing global variables:

Defaults paths:

  VisSimTools folder: /home/xyx/VisSimTools

  Output folder     : /home/xyz/VisSimTools/outputs

  elastix binaries are found in /home/matt/Downloads/Slicer-5.0.3-linux-amd64/NA-MIC/Extensions-30893/SlicerElastix/lib/Slicer-5.0/elastix

Thanks

Thanks for reporting, tge extension is not updated. Please use Slicer 4.10.2.

Thank you for responding.

Unfortunately, I am getting a similar error message with Slicer 4.10.2 running in windows and running on Ubuntu. Previously it was on 5.03 on linux.

The Ubuntu version produces a 1.2MB .nrrd file in /home/VisSimTools/ but I cannot get anything to display.

4.10.2 Windows error message

I will try to update the code next weekend. For now, please move the folder VisSimTools to your home folder. This should fix the path issue. Please notice that deep learning produces better spine segmentation.

[weemscreekstudios]

Do you have a recommendation for a deep learning module for spine segmentation?

Not sure as I used this some years ago, I think you may need to train the model yourself. You can check here https://deep-spine.de/
