Hi list, by applying the model reported above I obtained opposite maps for slope and intercept. E.g. In HC-MCI folder, the sig.nii.gz for slope and intercept show the same maps which inverse color (pos/neg). I guess that there is an error in my model for 3GV1. Please could you check in. Thanks Stefano
