Hi Matthieu
have you looked at the lh.inflated.nofix to see if anything major is wrong?
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

Dear Freesurfer's experts,
I have run recon-all on one subject and it stopped with a "XL defect

I looked at the ?h.orig.nofix but didn't see anything wrong, despite the fact
that these surfaces
are very not smooth.
What could I do ?
Best,
Matthieu
