mri_annotation2label enables extraction of vectors from .annot files to .label files, one file per label.

One may choose orig, white, or pial vectors.

(1) orig vectors are on the cortical surface.   The gray scale value for each of these is that of gray matter, correct?  And these are inside the pia and outside “white,” correct?

(2) white vectors are at the surface of the white matter just below the “orig” layer, correct?  Their gray scale value is that of white matter, correct?

Thanks,

Don
