Dear Ziad and Afni Experts,

I'm trying to compare cortical thickness for the affected hemisphere of a patient group to their unaffected hemisphere (the affected hemisphere is sometimes left and sometimes right, so it requires surface node/vertex symmetery). Is it possible to use SUMA_Make_Spec_FS to generate a SUMA surface from the lh.rh.sphere.reg (it's the output from freesurfer's recon-all with -contrasurfreg flag) ? I've already converted the .reg surface to .asc using mris_convert, but then running the make_spec does not seem to recognize/convert it to niml format as it does for ipsilateral surfaces. As an alternative, after generating both lh and rh surfaces in SUMA, is there a way to reorder the nodes of the right hemisphere to match the anatomy of the left hemi?

thanks in advance,
