Hi Jeorg
if the cluster is non-convex, the centroid is not guaranteed to be in the interior. Think of a C or U shape.

It is on a single subject on its on anatomy (self).
How are you determining that the centroid is outside of the cluster?
The coordinates are outside the cluster, there is nothing to worry about that.
It should give you a vertex number for the centroid (I think).
As you told in your last mail it gives Tal-coordinates and not vertices.
I opted not to use the centroid by default for this reason. This can happen because the centroid is irregular.
I don not understand this: What do you mean by irregular?
