Hi Siddharth

33364 is a pretty big defect and typically means something is pretty badly wrong with your data. This can mean that the hemis are connected, or attached to the skull or cerebellum. Take a look at the ?h.orig.nofix and see if you can figure out what is going wrong. You'll need to diagnose it before you can correct it (either by adding control points, or editing the wm.mgz typically)

Do anyone know how to fix this?
