hello!I would like to make the same crop change to N 3D-images（RandCropByPosNegLabeld）. What should I do? should I concatenate them? On which channel is the concatenation made? Hope to receive everyone's reply！

class SpatialCrop(Crop):

And you can find data shape assumption here:

Hope it helps, thanks.
