Dear Freesurfer Experts,
I am trying to combine aparc.annot with aseg.mgz for a Vervet monkey brain, the Aseg.mgz is hand made, not generated by freesurfer. so far I have no luck with it, So i've decided to go with a different approach, which is to add the Aseg (subcortical structures labels) onto the annotation file, then do a label2vol to convert annotations to volume. so I was wondering if there's any command to convert Aseg file into label or annotation format, thank you very much in advance.
Sincerely Andy
