[Freesurfer] WM lobes and Corpus Callosum

Hi,

I've been trying to create WM lobes using the following steps:

1) mri_annotation2label --lobesStrict

2) Outputting the labels from step 1, & creating a simpler annotation without limbic and insular lobes

3) Labeling the WM using mri_aparc2aseg (mri_aparc2aseg --s MySub --annot Step2AnnotationFile --labelwm --hypo-as-wm --wmpar-dmax 20 --rip-unknown

However, as the corpus callosum is not labelled as wm, it is not included in any WM lobe.

Is there any workaround to assigning the corpus callosum to the different WM lobes or do I have to manually edit aseg.mgz to change the corpus callosum's value to match that of WM ?

Thanks,

-Prad
