Setting an MNI origo to a volume

Dear Andras,

It would be a good thing to have in the first place!
Besides, I’m also interested in:
~ whether the MNI coordinate of a given point can be shown (e.g. in the Data Probe, or in another window)? /As sometimes we need to refer to these coordinates in the publications./
~ is there an option to re-set this MNI origo if I would like to change that to another point (to correct its placement)?

As I work work brain normalization for dog studies, the co-registration is the major part (which can be done well with the Transforms modul), but to visualize and analyze them in this common reference space (e.g., in MATLAB) we need to set manually an MNI-origo to a volume. Currently I’m only able to do that with the SPM, but it would be nice if I could handle the entire workflow with the Slicer.

Thanks for your advice!
Best regards, Kalman
