Thanks. To be clear, the models look correct but the images are transposed in I and J.
I did try negating the two elements on the diagonal directions, which worked except it also flipped the volume around its origin so the models were no longer aligned. My next step was to translate the origin. I didn’t want to get too far down this path in case there was something like a NRRD reader bug or something like that.
Shouldn’t NRRD capture this information and keep this problem from happening? Seems like the space should be specified fully. No matter what coordinate space the image is in, we should be able to get the data to display appropriately in world space. If this is a NRRD reader problem, I don’t want to have to un-workaround the problem for DICOM, for instance.
Thanks.
