Hello @Flemingjp,

The relevant class is [LandmarkBasedTransformInitializerFilter](https://simpleitk.org/doxygen/latest/html/classitk_1_1simple_1_1LandmarkBasedTransformInitializerFilter.html). [This discussion](https://discourse.itk.org/t/using-landmarkbasedtransforminitializer-for-bspline-registrations/4096/13) is possibly also of interest.
