Hi Bruce I need to know the transformation matrix itself since I will do the transformation in matlab. I successfully transformed white matter fibers coordinates to T1 using AIR 5.0 from LONI lab. They provide a transformation matrix. Now I want to transform the coordinates from T1 to Freesurfer space, so my question is: what is the transformation matrix that relates the T1 which I have used in freesurfer for parcellation and segmentation with the aparc+aseg.mgz file produced by FS? thanks JG
