Hi John,
Thanks for the clarification. I have the following images:
a) Warped (MNI) T1 brain
b) Anatomical 2 MNI diffeo transform (outline matches MNI template)
In my current status, based on your post I would not be able to perform the scaling. Is the following procedure below correct:
1) Invert the transform so that it is MNI (template) to anatomical mapping (the outline of which is in native space) and resample to match the native space grid (if it has extra padding)
2) Calculate the determinant of the jacobian of this transform
3) multiply the warped image by the determinant of the jacobian of the warp field
Thanks,
Ajay
