Hi Sita,
Running it with the -no-wsgcaatlas seems to do the trick as far as avoiding a segmentation fault. The T1 looks like it has a some motion artifact--might that be causing problems? I checked the Talairach transform and it looks generally alright, although I think it could be improved with some tweaking. It passed the automatic failure detection each time I ran recon-all, though. Would you recommend trying to improve the transform so that things down the line run more smoothly?
Best, Mike

Hi Mike,
Did you check the talairach. And how do nu.mgz and T1.mgz look. Also you could probably try running the following command to see if the skull strip step finishes without errors.
recon-all -skullstrip -no-wsgcaatlas -s <subjid>
Sita.

Hi Bruce, Nick,
I'm getting a segmentation fault that's crashing recon-all at the start of the watershed during skull-stripping. I've tried this three times, once starting the unpacking stream fresh from the raw dicoms, and it keeps happening at exactly the same place. I've been reconstructing brains of other subjects in the same directory all the while, so I don't think it's a permissions issue of any sort.
Full recon-all log is atatched, but here's the section where it crashes:
*************************WATERSHED************************** Sorting... first estimation of the COG coord: x=116 y=166 z=95 r=51 first estimation of the main basin volume: 585576 voxelsSegmentation fault Linux ba2 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:02:26 UTC 2010 x86_64 GNU/Linux
recon-all exited with ERRORS at Wed Mar 17 14:22:26 EDT 2010
And here's the OS data from the bugr script:
FREESURFER_HOME: /software/Freesurfer/4.4.0
Build stamp: freesurfer-Linux-centos4_x86_64-stable-pub-v4.4.0
Debian version: squeeze/sid
Kernel info: Linux 2.6.31-20-generic x86_64
Do you have any idea what might be going wrong?
Thanks! Mike
