Hi Douglas and Bruce,
I reran the recon-all with freesurfer/*MailScanner has detected a
possible fraud attempt from "7.0.0." claiming to be* 7.0.0.
<http://7.0.0./> Now it generated more files (57) compared to normal
run (81) in SUBJ/surf/ than freesurfer/6.0.0 (12)
The script didn't exit with error but stopped running after about
10hrs. Attached the log file.
The script ends with "
writing registered surface to ../surf/rh.sphere.reg...
registration took 0.35 hours

Is it still about topological defects? Attached the white matter
surface loading. It seems like there is no clear strip of the brain
skull on the right top, is that so?
Thank you so much !
Best,

Qi, in this context a "defect" is not just a place where the
surface is inaccurate. It is a place where the surface is
topologically incorrect, ie, a "handle" or a "hole" in the
surface. Such defects are quite common and usually fixed by
recon-all automatically. Sometimes the defects can be very
large. This generally indicates a problem with the skull
stripping or otherwise a failure to remove non-cortical
regions. Your job is to find where this region is and fix it
by fixing the skull strip or the wm.mgz file. Again, this is
not going to be a small error in the surface -- it should be
large.

Hi Bruce,
After examining the sagittal view of the parietal lobe, it is
fine including the area.
However, after examining the outputs in surf/, I noticed that
after it generated lh.defects, it stopped processing
lh.smoothwm and never got a chance to generate rh.defects.
Compared to normal subjects that successfully finished, there
is a clear mismatch between the inflated.nofix and the
brainmask & wm.mgz. Attached below.
Can you help confirm the fact of mismatch and let me know if
there is any way to fix this?
Thank you so much !
Best,
Qi

Hi Qi
it is not obvious from that one image that something is
wrong there. What
does a saggital view look like with the cursor on that
region? Also, can
you send an image of the rh.inflated.nofix in 3D mode?
Sometime XL
defects are fixable automatically, which may be the case
for your
subjects with very large ventricles, but sometimes not
cheers
