Operating system: Windows 10  
Slicer version: 4.11.2  
I am trying to get a volume rendering of my image stack, but it just shows up as a single weird black line (see screenshot)? How do I fix this?

It seems that you don’t have an image stack but you loaded a single image slice. Use the [DICOM module](https://slicer.readthedocs.io/en/latest/user_guide/modules/dicom.html#read-dicom-files-into-the-scene) for loading DICOM images and SlicerMorph extension’s [ImageStacks module](https://github.com/SlicerMorph/SlicerMorph/tree/master/Docs/ImageStacks) to load a TIFF/PNG/JPG stack.

The image that you loaded is a single slice, because it appears as a single line in the yellow slice view. If you load a 3D image volume then you see a 2D image in all slice views.

Ahh I see what you mean. I’m going to start from scratch and see if it does that again.
