Or the ?h.inflated.nofix can be helpful as well

I mean mris_fix_topology. Try loading the ?h.smoothwm.nofix in surface viewing 
(not in the volume). You can often see defects better on this surface (they 
look likes holes or handles; you should at least see some)

Hi Doug, when you say it did not finish, could you clarify what process "it" 
refers to?
I loaded the files you suggested and nothing popped out to me aside from the 
fact that the wm.mgz didn't seem to cover all the white matter.
Is it possible that topology error labels don't necessarily suggest that 
something went wrong and I can trust the results?
Thanks.

The topology error labels might be be created if it did not finish. YOu can try 
just loading the brain.mgz, the wm.mgz, and the orig.nofix and see if you can 
find a big topo error

Dear experts,

mris_fix_topology has been running for several hours now and the log suggests 
many more defects than normal. I tried to follow Bruce's advice from the thread 
here 
https://secure-web.cisco.com/11N_pSFTUOEZsMU7wtMNfIhMmRNWqmvsxTQeTGxdl-E3X_FJ9XkuZNLzTomdCZZwiiC6gS9oiXPNWh-M2KVbb9fP-1Qt7J-woH5hdLFg1otls4745ZoOKkz_-HOcFhenNfrq2-hdM_aX4I_g63u4rUe-NJLArGfWzCA77LLGm4lm0GK5kbCLf4Y6EqC9wHUUa-pdXC-7yMwNoi3Ips7HILVXXSdMEYlu_BPlUFIyI78yqCt3CSo6lAnlXS7QmRQY6JMl9WsV56bEMNqz44Bdlkw/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg03182.html,
 but wasn't able to load the &h.defect_labels as I received the error below.

Attached is part of the recon-all.log (starting from mris_fix_topology). Is 
there any other way to check/visualize what might have gone wrong?
FYI, I'm running recon-all thru the HCP Pipeline. Thanks!
