Do you think it would be of any improvement for a DARTEL-VBM approach to
normalise the images to MNI (using 12-P or 9-P) before segmentation? That
would avoid to have to change the code, but I´m not sure if the error is
bigger than the one introduced in the Dartel warp for different deformation
sizes.
