Hi Marie
for 2 you can do either mri_binarize --match or mri_extract_label. For 1 you can put your label into a .annot, then use mri_aparc2aseg (which is what we use to create the aparc+aseg.mgz).

Hi FreeSurfer team,
I have two small questions related to exporting label or aseg into mgz volumes:
I want to save one label into a volume, I used mri_label2vol which works perfectly, but I am getting only a thin label. I saw that I can use the --proj option with mri_label2vol to increase the "thickness" of my label, but I was wondering if there is any way to obtain the whole cortical ribbon corresponding to the label (i.e. something looking like the volumetric counterpart of the parcellation as found in the aparc+aseg.mgz)?
Similarly, I wanted to export the 5 subregions of the corpus callosum as individual volumes (i.e. one mgz volume for each subregions). Is that any way to do that? Or to export the 5 CC subregions as labels that could be then loaded on the cortical surface?
Many thanks for your help,
