[Freesurfer] from freesufer label to diffusion mask

Hi, all. I want to convert a freesufer label to diffusion mask with the following approach.

# tkregister2 --mov S0001_FA.nii.gz --noedit --s S0001 --regheader --reg register.dat

# mri_annotation2label --subject S0001 --hemi rh --outdir ./labels --annotation aparc.a2009s tkregister2 --mov S0001_FA.nii.gz --noedit --s S0001 --regheader --reg register.dat

# mri_label2vol --label ./labels/rh.entorhinal.label --temp S0001_FA.nii.gz --subject S0001 --hemi rh --o rh.entorhinal.nii.gz --proj frac 0 1 .1 --fillthresh 0.3 --reg register.dat

I wonder whether this is correct? In particular, what I am not sure about is the generation about the register.mat in the first line cmd.

Best, Xiang-zhen
