Thanks for the heads up, I managed to extract such information.
However I have encountered another issue with my data which is not directly related to Anatomical Orientation.
What I have is a CBCT which displays Coronal view first, Axial second, and I would like to transform it in order to have the Axial view first, which is what you expect from a CT.
Any idea on how to do this? I think permutation and rotation filters would be a good guess
