Hi Jennifer,
the spherical stuff has nothing to do with the CMA. And in fact the
spherical registration itself is not based on any manual labelings, just
estimates of cortical geometry from a set of training subjects. The
cortical parcellations do depend on manual labelings, but this is also
not the CMA. Rather there are two sets - one done by Rahul Desikan (39
subjects I think) and the other by Christophe Destrieux (12 or 14
subjects). The current spherical template we use is from the same 39 that
Rahul labeled.
cheers,
Bruce

Is any information about the manually-parcellated (CMA) training set used to
create the spherical template used in fsv4.*? The information reported in
Cerebral Cortex (2004) 14(1):11-22 reports 36 MRI volumes from an ongoing study.
Does this sound about right?
Or have there been any updates to the spherical template since then?
Many Thanks for any info,
Jenifer
