Hi Rick,
Thanks for your reply. I just want to make sure I understand this properly. You said that for a dataset to be oblique is just for it to be rotated relative to the cardinal axis. Initially, 3dinfo says that both my anatomical and functionals are oblique with the same degree of rotation. So why don't they align in the first place, when I look at them in the afni viewer (prior to running 3dWarp)?
Thanks!
