Bruce, No, I processed all of them the same way (converted files, -autorecon1, etc). The scan quality differs among them, but I tossed the really bad ones. Here is the xdebug file. Also, is what I'm seeing in this slice (see attached jpg) something to worry about? If I scroll through other slices, then come back to it, the artifacts are gone. This happens randomly on various slices on some of the subjects, but it never stays.
I have updated the drivers for the video card, and haven't had any issues (yet). I'll keep my eye on it. Thanks for your help. -Derin > were these processed any differently?
