Hi Bruce, Thanks for the quick reply.
I really need the sphere representation of the surface. When you say its harder, do you mean that mris_fix_topology wouldn't be able to automatically project it onto the unity sphere? I would need to make manual adjustments to fix handles and holes and then use mris_sphere to create the sphere surface? Can you please send more information about where or how it has been done before? Thanks in advance for any help, Leonardo On Fri, Dec 31, 2010 at 12:52 PM, Bruce Fischl <fis...@nmr.mgh.harvard.edu> wrote: > Hi Leonardo, > > we don't generate such a surface by default although we have created them on > occasion.
