Hi yujunjie

I'm not positive I understand the question. How do you define "better"? And what mri_convert command are you running? Our trilinear interpolation is nothing special - just the usual definition cheers Bruce On Mon, 25 Feb 2019, 1013364183 wrote:

Dear Bruce,   Hello, we used mri_convert ?Cvs [] ?CI [] ?Co[] ?Crt interpolate to perform the trilinear interpolation on the image, and also used the trilinear interpolation in the torch to process the image. We found the result obtained by the interpolation method in freesurfer is better than the result obtained by the trilinear interpolation method in the torch. Does the freesurfer perform other operations when performing the trilinear interpolation on the image? What is the principle?

Thank you!
