I need to split a bunch of images and corresponding labels in half. The images do not have the same dimensions.

I tried with the cropping tool, but I can’t get it exactly in half, I don’t know how I would invert the cropping selection for the other half, and I don’t know how I would copy over the “crop mask” for the labels.

Is there an easier way to do this?

ok, nevermind this - it’s just selecting a different volume in the “input volume” dropdown menu
