Hi Zach,

Precisely? No. There is nothing in afni_proc.py to produce
stats in orig space as if there had never been a jump to
standard space (not without changing a couple of options
and re-running the analysis, say).

But if you are not *that* picky, and just want to view the
results in orig space, then there is nothing extra to do.
Just view the stats as Overlay and set the orig space anat
as the Underlay. The afni GUI should automatically invert
the warp and transform the stats back to orig space.

Note though, unless the subjects are bolted down in the
scanner, they will usually rotate a bit out of plane during
scanning, especially in the nodding direction. At that
point, preserving the original grid gains almost nothing.
Even simple motion correction with 3dvolreg requires as
much interpolation as the transformation to standard
space.

Something to ponder...
