Hi,
I'm new to FreeSurfer and have been going through the tutorials, YouTube videos, and Mail Archive. I've run recon-all on a handful of scans with variable success. Some of the scans are processed after five or six hours without any problems, and the output looks good. Others are processed "without any errors" after a matter of minutes, and logically I don't see any output. Finally, others hit a hard error after a few minutes of processing during the talairach transformation step. I looked at the orig.mgz file (for the scan that failed at transformation step) through tkmedit, and it is a blank white rectangle. I don't see anything that resembles a head or brain. I've attached examples of each recon-all.log (i.e., good, bad, and bad_talairach). Any help would be greatly appreciated.
Thanks, Jared
