We have experiment on functional change based on PET in white matter and found that freesurfer's gtmpvc is very much helpful.

We would like to ask if we can get gtmseg to subsegment wm in to gyral based parcellation instead of lobar wm? We know that we can create our own segmentation based on wmparc.mgz but it would be better to have a more automate way.

On this matter, we also would like to add hippocampal subfield as segmented by "-hippocampal-subfields-T1" in recon-all for gtmseg results. Will this be allowed?

Best,

Jak
