Hello Lilla, thanks for the answer. I first used
bbregister --s (Freesurfer Directory) --mov b0.nii --reg .dat --dti --init-fsl Afterwards I made some minor spatial changes to the aparc+aseg, bringing it closer to what i believed its position was on the b0space: tkregister2 --mov b0.img --reg .dat --surf As far as I understand the aparc+aseg was the target and the b0 the space difining image. Now again the T1 should be the target and the b0 should remain constant. You mean that even if I want to register the T1 to the b0 i have to set the b0 as target?
