Dear SPM experts, I wounder if I can use spm two group t-test statistic inference in such a way. I perform DTI analysis and I have 2 groups' FA images. I try to compare their difference. If I did not perform spatial smoothing, could I still use spm statistic inference ? Should I still need to perform spatial smoothing in data image even I use snpm analysis? than is, no smoothing data can not enter into snpm analysi ? thanks for suggestion best JL
