Donna,
I have been writing to you about spherical registration. I am working
on implementing a landmark based registration approach and I want to
use Caret to learn about the currently accepted landmark placements
and deformation process. Using the tutorials, I have successfully
drawn the landmarks and run the spherical deformation. During the
deformation process, I get two error messages but both seem resolved.
“INFO: Border Link (0,6) in Landmark CentralSulcus does not project
to a tile and has been discarded.”
“Color ??? Specified multiple times with different color components.”
Are either of these messages a problem? How can I prevent these errors?
Also, I’m having trouble interpreting the deformation files and
viewing the results.
Why are deformed files created in both the individual’s directory and
the atlas directory? Is the spec file in the atlas directory the one
I want to use?
How do I know if the landmarks reach their target? Can I look at the
deformed individual sphere with both the deformed landmarks I created
and the original atlas landmarks, and compare these two sets of borders?
What are the difference between border projection files and border
files? I only have a border file for the atlas sphere.
I read a note on the message board about saving the border projection
files relative to the spherical surface, but this is not directed in
the tutorials. Is this a step that generally applies to surface
deformations?
What values do the columns of the border projection files represent?
Thank you for your help.
