Hi AFNI experts,
The anatomy dataset had been deobliqued using 3dWarp for each subject firstly: 
3dWarp -oblique2card -prefix card OriginalAnatomy+orig.
And then many ROIs were drawn on card+orig.
Now I want to transform these cardinal ROIs back to match the original oblique dataset (OriginalAnatomy+orig) perfectly.
And I have tried the method like this: 
3dWarp -card2oblique OriginalAnatomy+orig. -prefix reoblique card+orig.
But it doesn't work because the afni GUI said there is still oblique angle difference of 2.97 degrees between reoblique+orig. and OriginalAnatomy+orig.
Do you know how to process the ROIs to make them match the original oblique dataset perfectly?
I'm very sorry to disturb you.
Best regards,
Yu
