no, those are whole-brain parcellations so ever vertex is already assigned the most likely label for it

Ok perfect. Just one last question, how would I use the thresholded option
for the annotations (i.e. aparc.DKTatlas40.annot, aparc2009s.annot) when
doing whole brain analyses?
Thanks!

Great thanks Bruce! I'm assuming then that using the
thresh.label is the
best choice.

Hi Krista
the unthresholded labels give every point that
has a non-zero
probability of being in the label, no matter
how unlikely. The
.thresh ones are thresholded to pick the most
likely vertices
that give a label that is the right surface
area.

Hi, I've just started using the newest
freesurfer v
5.3 and I've noticed in
the labels folder that every .label has
a
thresh.label. When overlaying the
two, they can be quite different (for
example
MT.label is much larger than
MT.thresh.label) or quite similar
(V1.label is just
a tiny bit larger than
V1.thresh.label). What is the difference
between the
two and which is best
to use?
Thanks!
Krista
