Thank you for your suggestion! I will adjust the cropping and settings of my HN dataset accordingly.

Regarding the two affine registrations between the input and the template, are you referring to steps "B) Template co-registered (affine) to input image" and "C) Template warped (non-linear) to input image (only affine transformation in face/ear regions)" described in your manuscript? When performing affine registrations, does mri-reface segment the whole tissue area into different regions to calculate the cost function, with one affine registration specifically emphasizing the face area?

Best,
Du
