Lung segmentation

I am experiencing troubles when try to launch AI lungmask in the CT Segmenter module.
It reports the following note

Failed to compute results: [Errno 2] No such file or directory: ‘R231’

Any help?

Could you provide some more information?
On which operating system are you?
Which Lung CT Analyzer version do you use?

I get a good result with R231 lungmask AI:

Thank for the reply. I’m working on MacOS Monterey, the Lung CT analyzer version is 2.66. If I do the segmentation without AI it seems to work properly. When I add AI lung mask this is what I got

For the lungmask AI segmentation you only need to select “Use AI” and “lungmask R231”, then press “Start” and wait approx. 2 minutes. No placement of additional markups.
