[Insight-users] Limitation to the number of landmarks in FEM registration ?

[pierre villard]

Hello,

Is there a limitation in the number of landmarks that can be used in
the FEM registration method ?

I am doing a 2D registration with FEM and using a configuration file.
It works rather well without landmark but I would like to improve the
result using some manually "clicked" landmarks. It only works with 4
landmarks but I have 18 landmarks.

Is it a problem into my landmark file (here given) or a limitation in
the number of landmarks ?

Thank you,

PV
