Dear Doug, I figured it out. I wanted to relate a set of points on the pial surface to their corresponding Desikan indices and label names. If
[vertices, label, colortable] = read_annotation([some-path '\rh.aparc.annot'], 0); x=unique(label); y=sort(colortable.table(:,5)); Points labeled with 0 in x would correspond to index 1639705 in y Label 3294840 in y does not correspond to any points on the surface, and sends to corpus callosum.
