Did you check the talairach.xfm? Can you send us the recon-all.log file?

Sorry to add another!
I ran recon-all on a subject of mine, and have recon-all exit with the error below. Based on the message, I examined both T1 and nu.mgz. T1.mgz is in fact totally empty—definitely not enough values of 110. Is this due to a specific error that I might be able to bypass, or will adding in WM control points fix things?
Thanks in advance!

Problem in the COG calculation:
T1.mgz may not contain properly normalized white-matter.
Confirm that T1.mgz has enough white-matter voxels of value 110.
If white-matter contains few if any voxels of value 110,
try adding wm control-points to nu.mgz, and re-run recon-all.
