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.

were these processed any differently? The .xdebug_tkmedit should be in pwd wherever you ran it from.

Kevin- Yeah, either way. In my "infinite" wisdom I thought that scrolling slower would help, but not so.
Nick- I'm unable to locate a .xdebug_tkmedit file in either the freesurfer or subjects directory. Would it be somewhere else? It looks like we're using the 1.0-8178 Nvidia driver for our Quadro FX card, but their site shows a 1.0-8762 as the latest. I'll see if we can update it today, maybe that will help.
On the side... why are my intensity values "infinite" for the following subject? I've briefly checked brainmask.mgz, and differing intensities appear. Any ideas? Thanks.

Hm, I can't reproduce this.
So, you load up a volume, and repeatedly press an arrow key to scroll through the slices? Or hold the button down?

I've been experiencing some crashes/freezing using tkmedit lately, and have been able to reproduce it pretty reliably. It occurs when I scroll through the slices of the subject either using the arrows keys or clicking through on the toolbar. It happens when viewing a variety of volumes (brainmask, T1, etc), and from a variety of perspectives (coronal, sagittal, etc); it also happens on different subjects as well. This occurs no matter what workstation I use in the lab (networked environment). My X freezes up as well as the keyboard, but the mouse doesn't. I used to be able to restart my X remotely, but now tkmedit locks up so bad I have to reboot. Any ideas?
