I'm analyzing brain perfusion SPECT images using SPM, but my images are flipped compared to the SPM template. Unfortunately, the orientation matrix information is missing from the json file after converting DICOM to .nii. I'm looking for a solution to flip the images within SPM to match the orientation of the SPECT template. Do you have any suggestions?
Examples of images can be found here:
