Here's what I do:
For each subject run segment on the anatomic T1 image, choosing
'inverse' under 'deformation fields.' This will give you the inverse
Then inverse normalize the ROI mask using "normalize write" and the
iy_*.nii inverse deformation field.
Also, set bounding box to ones(2,3)*NaN AND set voxels sizes to [NaN
NaN NaN], based on the comment below from the manual.
Hope this helps!
From the manual:
If you have an image of regions deﬁned in the standard space, then the inverse
deformations can be used to warp these regions so that it
approximately overlay your
image. To use this facility, the bounding-box and voxel sizes should
be set to non-ﬁnite
values (e.g. [NaN NaN NaN] for the voxel sizes, and ones(2,3)*NaN for
the bounding box.
