Hi everyone!

I wanted to use the Segment Statistics module to validate the VOIs I segmented using Scalar Volume Statistic, but it doesn’t seem to be working in my 3D Slicer version 5.6.2.

Does anyone what this could be done to? What alternative could I use?

Thank you!

Greetings,  
Beatriz

What operating system do you use? Is there any error in the Python console or Error log after start-up?

I have Ubuntu 24.04 LTS system. On the python console it shows the following:

Thanks, this is very helpful!

First of all this means that the SlicerRT installation failed. I’ll look into this.

Second, the issue you posted about is probably due to the PET-IndiC extension, it seems that there was a change in the API that was not handled correctly. If you do not absolutely need the PET-IndiC extension, try uninstalling it and then probably the SegmentStatistics module will work.  
But in any case the owner of the extension should look into this.

Actually, Slicer 5.8 is around the corner. Can you try the latest Slicer preview version?

Thank you! I would really appreciate it if you could look into the SlicerRT installation issue cause I will need it.

I uninstalled PET-IndiC extension and the SegmentStatistics module works now.

Yeah I can try Slicer preview. Where can I find it tho?

One of the binaries is deployed in the incorrect folder. Please consider this folder:

 ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/9/9/995138d2dea7635caaa90dfd85a9191318d07fcb.png)

There is an `.so` file in `vtkIECTransformLogic` that needs to be moved to `Slicer-5.7/qt-loadable-modules`. This is for the preview, for 5.6.2 it is obviously `Slicer-5.6`. I did that and then SlicerRT worked correctly. We’ll look into the code to fix deployment in upcoming packages.

Thank you so much! I did the same for Slicer 5.6.2 and it fixed the errors I was getting on the python console.

No problem!

For reference, here’s the ticket to follow the resolution of the SlicerRT problem: [SlicerRT deployment fails on Linux · Issue #262 · SlicerRt/SlicerRT · GitHub](https://github.com/SlicerRt/SlicerRT/issues/262)

I added a new ticket in PET-IndiC as well (but not sure who will do it and when they will notice): [The extension breaks SegmentStatistics · Issue #8 · QIICR/PET-IndiC · GitHub](https://github.com/QIICR/PET-IndiC/issues/8)
