what viewer did you use to decide that they weren't consistent? On Wed, 15 Feb 2012, Jie Shi wrote:

Hi, experts. I have recently used mri_convert to convert some dicom files into both .nii and .img. But when observing, I found the image orientation of the .nii and .img was not consistent. Any idea about the problem and how to make them same? Thanks a lot.
