I'm not sure if you can use that or not. The best thing is to use bbregister to align the low-b to the anatomical, then use the resulting matrix as input to mri_label2vol.

Hello all,

I am using surface tracking in FSL to align my freesurfer surfaces to my diffusion data. I am wondering if it were possible to use the freesurfer2fa.mat registration file as the registration input for mri_label2vol. The freesurfer2fa.mat was generated using FLIRT in FSL by registering the freesurfer conformed structural space to diffusion space.

Ultimately I want to align the gyri and sulci volumes to the diffusion images I have. Is this a viable solution? Thanks in advance,

Tina Jeon
