Re: [Freesurfer] vertices are -1 when using vol2label

[Douglas N. Greve]

vertices require a surface. There is no surface for cerebellum, so the 
vertices are all marked -1 to indicate that the vertex indices are not 
valid. The XYZ values are valid though

Hello!
I'm trying to convert the cerebellum cortex in the aparc+aseg.mgz into 
a label so I tried:


mri_vol2label --c bert/mri/aparc+aseg.mgz --id 8 --l lh.cerebellum.label

but the resulting output file only has -1 as vertices. Is there 
anything wrong with the command above?


Best regards,
Sam
