Dear freesurfers I used bbregister to coregister diffusion images with anatomical. I would like to apply the bbregistration transformation to the white and pial surfaces What I've done is: I calculated new transformation matrix using fs_read_dat.m and then apply it to the surfaces with mri_surf2surf. When overlaying the new surface on the diffusion data- it seems that the transformation is inaccurate.(screenshot is attached) Any idea why?.
Thanks, Shani
