Operating system: MacOS Ventura 13.1  
Slicer version: 5.2.2  
Expected behavior: After rendering the volume and cropping the 3d view, when I go to the Filtering-\>Denoising-\>Gradient Anisotropic Diffusion menu, I should see my volume in the Input Volume Section  
Actual behavior: My volume doesn’t show up

Gradient anisotropic diffusion (and most other modules) requires a scalar volume. You can convert vector volumeto scalar volume using “Vector to scalar volume” module.
