External Email - Use Caution Dear all,
I have a question about left-right sphere based co-registration. I have a scalar quantity defined on the fsaverage5 ico5 surfaces and I would like to map left to right hemisphere. I’ve computed left_right registered spheres by running following commands in the fsaverage5 folder: mris_curvature -w lh.white mris_curvature -thresh .999 -n -a 5 -w -distances 10 10 lh.inflated mris_left_right_register lh.sphere rh.sphere lh.sphere.left_right rh.sphere.left_right mris_curvature -w rh.white mris_curvature -thresh .999 -n -a 5 -w -distances 10 10 rh.inflated mris_left_right_register lh.sphere rh.sphere lh.sphere.left_right rh.sphere.left_right As far as I understood, the lh.sphere.left_right contains the lh mesh warped to be consistent with the anatomical landmarks on rh. Thus in mapping or interpolating, I have to use vertices in lh.sphere.left_right and map/interpolate them to rh.sphere. Is that correct? There is a better way to do that? Moreover I cannot find information about the “thresh” and “distances” arguments in mris_left_right_register help. Maybe those options are not fine for the fsaverage ico5 ? Thank you all in advance.
