Hi Leonardo, you would need to connect the 2 ?h.orig surfaces, then I guess try running the combo through mris_sphere and mris_fix_topology. No idea what the results will be as we've never tried such a thing. Or maybe you should correct the topology first then create a topology-preserving connection if you can, and just run the combo through mris_sphere.
