is that the orig surface? Usually that's what is displayed in green (the white is in yellow). This kind of thing usually means an incorrectly fixed topological defect, so the best bet is to manually correct the defect. Bruce

Hi, I've just installed the newest centos-dev version. I did a rerun on some of my subjects, and in one particular subject the white matter orig-surface didn't follow the white matter volume at the right hemisphere. It looks like the surface takes some 'shorcuts' passing through gyri and over sulci. This only happens in the right hemisphere, and it didn't happen in the previous version. (I've attached an image to illustrate) Do you have any idea what causes this, and if so, what I can do to fix it?
Also, I'd like to know if the talairach-conversion has any significant impact on the final result, so that I should try to obtain the lowest 'Final objective function value' by applying the tecniques suggested in your tutorial.
