Hi Jared
for the ones that run quickly and end, it's because you haven't told it to do anything. The first couple of lines of the recon-all.log file give the command line as:
Thu Dec 5 14:00:18 MST 2013 /mnt/NAS3/freesurfer/freesurfer//bin/recon-all -i Time3_28908_s11038064-0005-00001-000001-01.nii -subject Time3_28908
this will just convert the nifti and create the subject dirs for Time3_28908. You need to add "-all" at the end of the line, as you did in the other ones.
For the one that failed the talairach it's hard to say. You are starting with nifti - can you try it directly on the dicoms? Where did you get the nifti from? If you bring the nifti input volume up in freeview does it show in the correct orientation? That is, is what freeview thinks is anterior truly anterior, etc....?
cheers Bruce

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
