Mrregister- 2D

Hello everyone,
I am new to MRtrix as well as to image processing. I am working on Fetal MRI. Is it possible to register two 2D images (2 slices of a sequence) using mrregister.

Thank you in advance.

mrregister was designed for 3D and 4D images and has no options to constrain registration in certain directions. I’d recommend you have a look at antsRegistration (for instance and convert the resulting transformations if needed.

Thank you very much. I will check that
