Hi Rishi,
When you actually ran the registration, did it complain about crossovers?
It's not hard to get weird results when viewing registration results,
because your deformed spec file has files from both source and target.
For example, deformed flat maps might look funny if not viewed with the
right topo file.
But your "resampled" fiducial surface (David doesn't like the word
deformed in this context) should look reasonable when viewed with the
atlas target closed topo file. And one should not get lots of
crossovers on that surface, unless you choose the wrong type (e.g., flat
or spherical). If you like, I can have a look at your source and
target, so I can see whether anything is really wrong, and if so, offer
advice on how to fix it. Upload a zip containing source and target
directories here:

Hi,
I have registered (spherical registration) my macaque surface to a
macaque atlas......and upon viewing my surface, the cortical areas
seem to be demarked appropriately, but I have a high number of
crossovers (when i do a surface crossover check).........what do these
crossovers mean? could my registration be more precise?
thanks
rishi
