Hi This is Johnson, I am researcher at univ. of IL at chicago, I have a question regarding freesurfer: What is the transformation matrix that relates the freesurfer aparc+aseg space to the aparc+aseg-in-rawavg space, I am asking this question for the following reason: I have white matter fiber tracts in Diffusion space, I managed to transform it to aparc+aseg-in-rawavg space by registering the B0 to the brainmask-in-rawavg volume. Now I want to transform it to aparc+aseg space. thanks
