Hi Donna,
I replicated your probelm exactly with the roi.zip archive you
uploaded. It contained only the flat coord and cut topo; have you
tried using the fiducial coord with closed topo? It may not help, but
it's worth a try.
Yes, the problem persists.
Although the clusters using metri
Hi Mateus,
It's true the top cluster is mostly dense, but look at the node I've
highlighed in red in the attached capture. I wonder whether nodes like
this that "cinch" the cluster cause the algorithm to give up.
Attached is some code I dug out of the source that might be what Caret
is actu
Hi Donna,
Thanks. I will look at the code and I let you know if I find something.

Hi,
I would like to calculate the center of gravity (COG) of a surface ROI.
I see that 'Surface Region of Interest':'Statistical Report' gives me
that information. However, if the nodes distribution over the surface is
not uniform, the COG is biased toward the more dense regions.
I understand
Mateus,
You raise a good point.
In practice, it seems that you should keep the uneven distribution of nodes.
The reason is as follows: If you resample the nodes to a more sparse uniform
distribution, then you will distort the surface to some degree. The surface
distortion will inevitable shif
Hello,
I'm new to caret. I've created an inflated surface using the
Colin-SPM2-L/R fiducial and would like to save this inflated surface for
future mapping of functionals data.
If I'm correct, it's simply a matter of File - save data file - save as
a "scene".
However, when reloading the spec file
Hi Gene,
It sounds like you've actually created a new coord file -- an inflated
version of a the colin SPM2 fiducial. So if you wanted to use this
later, you'd need to save it as a separate coord file. Then you could
use D/C: Scene to append a scene using this coord file, and then save
the
