[Freesurfer] Freesurfer and 3D true - IR sequences

Dear all, I have a set of 3D true IR volumes acquired on a Siemens Avanto Scanner 1.5T. The GM/WM contrast is very good and the images look better (from a neuroradiological point of you) than the classical 3D T1 we usually acquire. The sign of the images (that in this sequence could be <0) could
