Dear expert,

Recently I saw a paper mentioned this :

By using the *deformation field* from nonlinear registration, we can build
> the correspondence between voxels in the template and each linearly-aligned
> image.  For instance, for each voxel (x, y, z) in the template image, we
> can find its corresponding voxel (x + dx, y + dy, z + dz) in each
> linearly-aligned image, where (dx, dy, dz) is the displacement from the
> template image to the linearly-aligned image defined by the deformation
> field.



So, I want to get the deformation field from the template to the* linearly
registered image(flirt_T1)*. I tried like this :

*flirt **-in betted_T1.nii.gz **-ref Template_without_skull -omat
flirt_transf.mat -out flirt_T1*
*fnirt --in=*  *betted_T1**.nii.gz* *--ref=* *Template_without_skull*
*.nii.gz **--aff=flirt_transf.mat --cout=warp_coef -fout=warp_fout*
*fnirtfileutils --in=warp_coef.nii.gz --ref=* *Template_without_skull*

*.nii.gz --out=fnirtfileutils_fieldinvwarp --ref=flirt_T1.nii.gz
--warp=fnirtfileutils_field.nii.gz --out=invfield_mni2flirt*

I want to know if the *'* *invfield_mni2flirt**'* file I got is the
deformation field of the image I want from the template to the
linear registered image(flirt_T1)?

Best wishes,
ping
