Dear SPM users: I am an undergraduate research assistant and start to learn SPM. For testing purpose, I use MR image as both reference and source images for registration in SPM5. In theory, there is no need for translation. But I found there are translation components in the equations (see attachment). Why? By the way, how do I know how well the registration is ? Are there any criteria to check ?
