[Insight-users] Manual selection of control points

[Ganesh Narayanasamy]

Hi, 
 I am working on 3D-CT image registration problem. I start with performing affine registration on coarse images followed by a non-rigid registration (Demons or B-spline) on fine images. 

a) Is there a code for manual selection of control points that could guide the affine and then the non-rigid registration module?

b) Once the registration is done, I would like to evaluate the registration error using a different non-rigid registration technique (say, Thin plate spline). This would need another set of manually selected fiducial markers on the fixed and the registered image volume. My question is: Is it possible to apply the non-rigid transformation parameters on these fiducial markers and get its corresponding coordinates in the new image space? 

Thanks,
Ganesh
