Hi Don
the defect is too big to fix, and probably means something dramatic is
wrong (e.g. skull or cerebellum attached to the brain component of the
wm.mgz). Check out the ?h.inflated.nofix and see what is going on and
correct it before rerunning
cheers

I have run freesurfer 6Beta on the scan with very large CSF spaces
With flags: -bigventricles and –notal-check .
I used the latter flag per suggestions in the log as the first run failed on
a talaraich check.
This second run appears to be hung as it has not written anything new into
the recon-all.log file for 7 hours.
I would like to restart this at a reasonable point rather than at the
beginning.
Can you recognize where it is and what is are suggested restart flags?
