AFNI gurus,
I came across this post looking for any guidance on which interpolation method is best for 3dvolreg as well as 3dtshift.
I don't mean to belabor this but on the help pages, -Fourier is stated to be the most accurate for 3dvolreg and 3dtshift. However, in afni_proc.py the default for 3dtshift is set to -quintic and for 3dvolreg it is set to -cubic. We are working with standard un-masked functional data.
It may simply be that they all work about the same, but any updates/suggestions/disambiguation would be greatly appreciated!
