It is on a single subject on its on anatomy (self).
How are you determining that the centroid is outside of the
cluster?

Hi Jeorg

Hi,
I am sorry to disappoint you. I wrote another srcipt to compute the centroid in
order to clarify whats happening. The centroid computed by the script is in the
center of the cluster. However, the differences could be due to details of the
computation. I was not able to unriddle all the
Hi,
you are right! The Talairach ccordinates change. Unfortunately, the centroid
coordinate of my data are outside the cluster. Do you have any suggestions
about that?
I also tried your version of the script. The following message appeared:

I've put a copy of my version (for linux) here
