Hi Dorian,<div><br></div><div>I talked with our lab members.</div><div>You need to use landmark-based alignment. For example, you can identify anterior and posterior commissure at the mid-sagittal level, place landmarks, and do alignment, which can take the tensor file and do tensor rotation.</div>

Hi MRIstudio list,<div><br></div><div>I am returning to a previous topic with a detaled question. What would be the formula to rotate the 6 tensors in space? DTIstudio cannot rotate tensors manually but perhaps I can do this in Matlab. I need to do the rotation to save some LDDMM transformations which always involved preliminary manual rotation. Without it, I would have to run again AIR and LDDMM on each subject.</div>
<div><br></div><div>Thank you.</div><div><br></div><div>P.s. If anybody knows how to read .dat files in Matlab, that may be a lot helpful too.</div>
