Hi, Ptaylor,
Thanks for your reply!

I ran the script what your suggested and got the followed result:
3dinfo -is_oblique mag_res_brain.nii.gz
0
3dinfo -is_oblique CEST_res_brain.nii.gz
0

I tried other way to rotate the mag to match the CEST orientation, then align mag to CEST with 3dresample -master CEST.nii -prefix mag_to_CEST.nii -inset mag.nii, is this right one to align mag to CEST image?

Thanks!
