Initial release of the .otl (outline files) version of the
segmentation data for this release. While the .nii version of
the segmentation were originally released, those files are derived
from the cardviews-based .otl files which provide the 'outlines' of
each neuroanatomic structure. While the format of these files
is a bit obscure, they do represent the true 'raw' segmentation
data that was in this article.
