Hi Corey,
something is very strange with that volume. Is it really only 77 slices? It
doesn't show properly in tkmedit, which means that the direction cosines
are probably messed up. The voxel sizes may be wrong too, as it looks very
odd. Do you have dicoms for it?

So far I've identified and ruled out three possible reasons why this could
be happening.
1. The localizer slice as the first slice in the volume. I removed that
slice in the volume and tried again.
2. The field of view did not encompass the whole head in the
anterior/posterior dimension, so I zero padded the edges - still didn't
work.
3. The in-plane resolution of each slice is 512x512, which I learned from
the help archive may be problematic. So, I tried both downsampling the
volume and re-running autorecon1 as well as keeping the native resolution
and giving autorecon1 the -cw256. This still didn't work.
Please help.
Thanks,
Corey
