Dear AFNI experts,
I would like to compute standard deviation maps for individual subjects with partial-brain data acquired in oblique orientation. I tried using 3dTstat on un-preprocessed data and got the following message:
WARNING: If you are performing spatial transformations on an oblique dset,
such as TRAIN1.nii.gz,
or viewing/combining it with volumes of differing obliquity,
you should consider running:
on this and other oblique datasets in the same session.
See 3dWarp -help for details.
Can someone provide me with more detail about the implications of computing a standard deviation map using an oblique dataset? I’d appreciate any additional information!
Thanks so much,
