Hi, These terms mean the same thing. All the best, Mark Adi Maron-Katz <[log in to unmask]> wrote: Hello again, I have a question concerning normalization: Is there a difference between normalization of fMRI images to MNI space (as can be done using SPM, for instance) and registration to MNI152, as can be done using FEAT? If there is a difference, can normalization be performed using your tools? and do you recommend it? Thanks Adi
