Hello! I need help. I’m trying to segment lumbar spine DICOMs, but whenever I click **Apply** , my computer freezes and the segmentation never finishes.

It seems that you have run into the same issue that was reported here:

> <https://github.com/lassoan/SlicerTotalSegmentator/issues/79>

> When running the segmentation plugin, the 3D slicer becomes unresponsive and can…not be operated.

Unless someone else have time to investigate this earlier, I’ll try to have a look at this next week.
