Dear SPM community,

I was trying to implement the Geodesic shooting registration algorithm the same way I usually use the DARTEL registration (in a pairwise registration) and I which to have some feedback whether I am doing this correctly. The results seem ok but does not seem to improve over DARTEL.

Implementation:
1. segmentation of both images
2. import to DARTEL
3. SPM shoot template
4. SPM deformations
    ->deformation field A
    ->inv composition
    ->->deformation field B
    ->->space: B
    -> id space: B

Thank you.
