Does anyone on this forum know AMIRA segmentation software? I have resliced/reoriented an anatomical image (.nii) in SPM. When I open the resulting image, it is nothing but a gray square without intensity values (NaN). Further, I want to register/reorient label fields made in on the original anatomical image in AMIRA so that they match the orientation of the resliced image. It appears to be possible to register the new anatomical orientation to the old label field orientation but not the old label field orientation to the new anatomical orientation. Does anyone have suggestions?
