Hello Freesurfer experts! I need to compare one patient to a group of controls and I wanted to know which is the best way to do this. Is it correct to do it with group analysis when 1 group only has one patient, thus no stdev, and the other group (controls) has for ex 20 patients? Is there a better choice for this situation or a prefered way to visualize result in this case?? Thank you! Mercedes
depends on what you want in the end. You can do that analysis, but p-values will be meaningless. Do you just want the difference between the subject and the group mean? If so, that will work. It should also give you z-values if that is of intereest
