I apologize but I'm not familiar with the term bounce; do you want me to re-run the mrisp_paint-command but with specifying the optional #3 parameter for the <template_fname> argument? The sphere and the inflated surface look more similar but still seem to
differ from the fsaverage that way.
Sorry, been trying to get this right for some time before getting back to you, but not sure that I have. I'm attaching screenshots of the ?h.sphere.reg for the original, processed and the fsaverage-subjects with the destrieux-annotation. To me, it looks slightly
worse after the mris_register command. Not sure that I've managed correctly with the mrisp_paint
(mrisp_paint $FREESURFER_HOME/average/?h.average.curvature.filled.buckner40.tif surf/?h.sphere.reg ?h.sulc_test) but attaching a screenshot from there as well.
Would be happy to know what I could alter to get it more accurate!
Kind regards,
Carl
