also, if you run defect-seg, it will create a segmentation of the
defects which you can visualize in the volume. Run defect-seg with
--help for more info

Hi Ricky
how did you try to load the defect_labels? The end of the
recon-all.log file lists a defect with 26K vertices, which is probably
too big to fix (it's about 1/5 of a normal surface). You should be
able to visualize it by loading the lh.defect_labels file as an
overlay on the lh.inflated.nofix and lh.orig.nofix surfaces. Make sure
to change the threshold for the overlay to 0, then finde defect #116,
which is the one it is stuck on. I think we actually add 1 to the
index in the labels file so that non-defective vertices show as 0, so
it may be 117. It should be clear though as it will be a lot bigger
than others
cheers

External Email - Use Caution
Hello Freesurfer experts,
I am trying to run recon-all to assess cortical thickness on a 3D
FSPGR+C
scan. The run keeps timing out during the fix topology lh step. I have
looked at the resulting images and I am not sure whether I need to
fix the
white matter, add control points, or do something else entirely to
fix the
problem. The lh.inflated.nofix does not seem to have anything
unwanted still
attached and the lh.defect_label will not load. The lh.inflated.nofix
does
show some areas that have strands/spikes, which I think might be due
to the
gadolinium contrast. I wanted to ask for opinions on how to proceed.
I have
attached the recon-all.log.
