QSphere (-<no>qsphere)
This step performs a quick (hence 'Q'sphere) spherical unfolding and is the initial step of automatic topology fixing. It is a quasi-homeomorphic spherical transformation of the inflated surface designed to localize topological defects for the subsequent automatic topology fixer. Calls mris_sphere. Creates surf/?h.qsphere.nofix.
