No subject

exactly is the problem that you are facing.


Your approach seems to be reasonable:

A) Perform PointSet to PointSet registration
B) Take the resulting transform
C) Resample the moving image.


Something that might be confusing in this process
is that the definition of the direction of the Transform
in PointSetToPointSet registration is opposite to what
we use in ImageToImage registration.

Therefore, for resampling the moving image, you may
have to use the inverse of the transform that you obtain
from the PointSet registration process.
