Hi all,

I have a nifti file f.nii whose size is 80*80*60*266, (266 is the TRs). Using "mri_info f.nii", I can see that its orientation is is PIL. I want to change it to RPI. I do the following: "mri_conver --in_orientation PIL --out_orientation RPI -i f.nii -o f.rpi.nii" It give me f.rpi.nii, which has an orientaion of RPI. The problem is that f.rpi.nii is 80*80*60. It contains only one volume. How can I get a reoriented volume that has the same size as the original 80*80*60*266?

Many thanks.
