Hi Ping
we don't apply the linear registration to any image - we use it to
initialize the nonlinear warp. And yes, the nonlinear warp is stored as a
128^3 array with 2 voxel spacing and interpolation between them. You can
visualize the .m3z directly in freeview as a 3-frame displacement volume

Dear Tim,
Thank you for your reply!
1) I want the the deformation field is the displacement from the template
image to the linearly-aligned image defined.
2) I just use the recon-all to generate the file.
3) What I want is to first linearly register t
Hi Ping
the displacement fields are stored in m3z format in the file
talairach.m3z. They are a vector field over the atlas that maps points in
the atlas to points in the original (not linearly aligned) space.
cheers
Bruce

Could you explain what you are trying to achieve and which transformation you
are referring to? I don't get:
1) what are the input and output files of the registration for which you want
the deformation field?
2) What command did you use to perform th

Dear expert，
I saw a paper mentioned this ：
By using the *deformation field* from nonlinear registration, we can
