It seems that it, in terms of data integrity, it may be best to oblique the anatomical image. I tried doing this on the dataset that you looked at, however, there was no visual change (although the version of AFNI wasn't showing the EPI as oblique...as you noted). With the newer version of AFNI, should I expect to see a visual change in the data when I oblique the anatomical? I'm guessing that this step should be done before talairaching (and of course co-registration to the EPI). I'm also assuming that by doing this, the anatomical data will be interpolated, so any structural data processing should be done on the original dataset. Correct? Again, I appreciate your help!
