I don't think we have anything to create the deformation field explicitly, unless Thomas Yeo (ccd) does.

Hi, Bruce,

Thanks a lot for replying me.

Do I have to create the deformation file by myself? Or can it be generated from some option set in mris_register?

Thanks again.

Best,

Hi Xiaojing,

the deformation map is the difference between the ?h.sphere.reg and the ?h.sphere. I guess you would want to represent them as arcs of great circles.

Hi, all,

I have a question regarding how to get the deformation map in surface-based registration. I am wanting to use mris_register to align two surfaces. Can I get the deformation maps describing the vertex-to-vertex correspondence? How can I get it?

Thanks a lot.

Best,

Xiaojing

It is possible to do this sort of thing in Caret (using the FreeSurfer registration); one can create a deformation map between sphere and sphere.reg. What do you need the deformation map for?

I don't have it either.
