Sure. Since it's probably a bit big for email, I uploaded it to http://dl.dropbox.com/u/432093/ANALYZE.zip

Can you send us the analyze files?

I actually didn't know you could load analyze into tkmedit, but now that I have, it does look like that too (just without the direction arrows). It doesn't look like that when I look at it in other viewing programs, though (it looks like you'd expect).

Does it look like that when you load the original analyze into tkmedit?

Sure. Here's a screenshot of the orig.mgz.

Can you send us an image? The 16 bit shouldn't be a problem Bruce

The orig.mgz shows up with weird colors (the grey matter is black, the background is light gray, and there's a white halo around the brain and in the ventricles/CSF).
Another possibility I just thought of is that the original ANALYZE image is 16-bit, and is 230 x 230 x 230 voxels. Does mri_convert (or any of the downstream programs) expect the scan to be 8-bit and/or a different size?
Again, like I said, I'm completely new to Free Surfer (just started trying to figure it out today), so sorry if this is an obvious first thing to check.
