Dear SPM experts,
just a clarification about the reference system for "Realign & unwarp". Do x y z for the first-order and second-order effects correspond to world space or do they correspond to voxel space? As the idea is to correct for out-of-plane rotations it seems to be the voxel space, but the current desciption including x y z is somewhat ambigous.
Best,
Helmut
