Hi, I was able to successfully use IGT Fiducial registration wizard for manually registering images (with “Transform” option set to “Warping”, which uses thin plate splines) . Next I would like to use the generated transform file independently to map separate set of points from ‘From/Source’ image space to ‘Target’ image space (and vice versa).
I tried two approach:
- Trying to export transform as deformation field nrrd-> Fails with an error “Cannot save FILENAME to FILENAME.nrrd”
- Trying to load the saved transform into using itk::TransformFileReader → ITK seems to not recognizing this type of transform - “ThinPlateSplineKernelTransform_double_3_3”
It’s looking like my only recourse would be to bypass the transform file entirely and only store the fiducial points and load them in ITK and create the transform there directly.
Thank you for the wonderful tool! Would appreciate any more direct way to resolve this issue.
