Hi all We want to reorient the spm5 beta file, say beta_0001.hdr (img). And we want to apply the reorientation on the actual image but not the head file. However, spm seems only change the head file, because when we replace the reoriented .hdr file with the the original .hdr file, the image looks without orientation. Can somebody tell us how to apply reorientation on .img file? Thanks xiang
