Hello Freesurfer Experts,
I ran into the following error when running Freesurfer for one of our subjects, during:
mris_fix_topology -mgz -sphere qsphere.nofix -ga FirstOrderPoly lh
I could only find a partial answer to a previous post on a similar problem - pasted at the end. Following that, I looked at lh.orig.nofix surface - screenshots attached. I am not sure whether its alright. No rh surfaces were created.
Please let me know how to correct this problem and proceed further. Quick response will be greatly appreciated,
Pradeep

For the lh, there is no cerebellum and no skull, looks to be correct.
I don't see any rh* files though?

yes, mri_ca_register takes a long time. The good news is it works really well :>. As for the mris_topology_fixing problem, what does the ?h.orig.nofix surface look like? Does it include cerebellum or skull?
Does
it look approximately correct?

Gave the new dev version a spin with autorecon-all, couple of things...
For the mri_ca_register step, it took a total of 791 minutes! Is this normal or could this be a hint as to things going wrong early in the pipeline?
Also, the program eventually crashed during the error correction, below
are
the lines that seem like they may have had some effect:
Anyone else experience this problem?
Thanks
