Hi Stefan, Without having a look at your image data, I would say that the initial translation is most likely due to the initializer that is used before starting the registration.
Let's say you have already manually registered your moving image quite well to the fixed image and now you want to start the automatic registration. The initalizer has two options (in the GUI) the first one is to initialize the two images using their geometric centers. The second option is to use the center of gravity based on the grey value representation in the images (can be useful e.g. for head images). Unfortunately the UI doesn't allow for a initialization as is, which would use the manual initial transformation. At least not in our version, maybe things have changed in the new MITK version. I hope that helps a bit! Best, Matthias -- Dipl.-Ing.
