I believe it does, although the integral values are a bit suspicious.
Maybe Doug or Nick knows?

hi bruce,
i visualized these two subjects using freeview and nothing looked out of the

does this generation take partial volume into account? this is the default
output from running recon-all (from 5.1.0).
cheers,

Hi Satra
this seems vanishingly unlikely to me, particularly with partial
volume correction. Have you visualize some of the subjects that
have the same structure volume?

a quick update. the following fiddle will show the
number of subjects that
have an identical the same Right Amygdala volume. It
simply plots a
histogram of the counts per volume (scroll to the
bottom of the result
window).

hi,
trying to figure out the likelihood of identical
subcortical volumes
across individuals. i'm noticing this in some data
processed with
FreeSurfer 5.1.0.
just to give some probabilities - these are out of
about 963
participants.
and there are several such small clusters of
identical numbers - never
exceeding 6 participants i believe.
cheers,
satra
