Hello @NPi,

Welcome to SimpleITK / ITK!

First the “bad” news, SimpleITK does not provide support for point set to point set registration (for point data, only the rigid/affine paired point case is currently supported).

ITK does support point set registration, see the [PointSetToPointSetRegistrationMethod](https://itk.org/Doxygen/html/classitk_1_1PointSetToPointSetRegistrationMethod.html), and relevant discussion found [here](https://discourse.itk.org/t/speeding-up-point-to-point-registration/2711).

If your data are intrinsically point sets you might consider looking at tools that only focus on points such as the [Point Cloud Library (PCL)](https://pointclouds.org/).

Finally, if you have the time and want to learn SimpleITK in an organized fashion, try [the online tutorial](https://simpleitk.org/TUTORIAL/).
