Description

Hello @NHPatterson, I am encountering an issue with image registration, specifically in scenarios where different modalities are registered independently, and I need to merge their transformations without repeating the registration process.

To illustrate, I have two separate registrations: modality_1 with modality_2, and modality_2 with modality_3. Is there a way to extract the transformation information from these registrations and apply it directly from modality_1 to modality_3 through modality_2?

I know that redoing the registration with all modalities is a solution but i was wondering if maybe I can use the already built codebase to read the transformation from disk an apply them.

Thanks in advance 😊
