Slicer not loading a radiotherapy plan and dataset

Operating system: Windows 7

Slicer version: 4.8.1

Expected behavior: To be able to examine and load a radiotherapy dataset without errors

Actual behavior: I receive the following errors when trying to ‘examine’ my data:

Error1

and then when I ‘load’ the data I get the following error,

Any help would be greatly appreciated. I have run this dataset on my personal computer with no issues. So, I expect there may be some issue with the hospital network on the computer I am trying to run this on

Many thanks!

Check out tips on DICOM FAQ page. If you cannot resolve the issue then the best would be to share a phantom or anonymized dataset with us.

My DICOM dataset is not the issue I’m fairly sure. This is because I have Slicer installed on a personal laptop and can load the exact same dataset with no issues.

However on my hospital computer I run into the issues posted above. I have attempted the tips on the DICOM FAQ page with no success.

I have attached the error messages I receive in the python console when simply starting Slicer,

It seems that SlicerRT extension installation is corrupted. Please try to uninstall SlicerRT and reinstall.

Hi Andras,

Thanks for your speedy reply. I just attempted an uninstall and reinstall of Slicer 3.8.1 and then an install of SlicerRT but I still get the same error messages upon starting Slicer,

Hi Andras,

OK I have fixed my problem, although I have no idea why it was an issue. For some reason Slicer wasn’t reading the SlicerRT extension’s qt-loadable-modules in the ‘Additional module path’

So, I copied those files and placed them in the ‘Slicer/lib/Slicer-4.8/qt-loadable-modules’ path

And now it seems to work fine

Thank you, as always!!
