External Email - Use Caution Hi Bruce, I don't see major thing that could be wrong. I uploaded on the FileDrop the subject directory compressed. Could you have a look at it and tell me what you think ?

The code doesn't exit when it detects an XL defect - it just warns you and doesn't search as thoroughly for solutions (which would take forever). It sounds like the 0 faces error is your problem, but they are likely related. Take a look at the inflated.nofix and see if you can identify the XL defect. It is probably near the back of the brain since it is one of the first defects encountered. cheers Bruce On Mon, 18 Feb 2019, Matthieu VANHOUTTE wrote: External Email - Use Caution Dear Freesurfer's experts, I have run recon-all on one subject and it stopped with a "XL defect detected..."
