Dear AFNI experts,

I faced the below error message while running resting-state proc py (example 11).

*+ WARNING: If you are performing spatial transformations on an oblique dset,
such as ./vr_base_min_outlier+orig.BRIK,
or viewing/combining it with volumes of differing obliquity,
you should consider running:
3dWarp -deoblique
on this and other oblique datasets in the same session.
See 3dWarp -help for details.

I checked the copy_af_FSvent+orig and it looked fine (please see attached) and only this subject's data showed an error message. Could you please let me know what could be an issue here?


Best,
