Hi Christian, if you send me that surface, I can take a look at what's going wrong.
best Andrew

Hi,
I got the following error running mris_topo_fixer:
~$ mris_topo_fixer -mgz -warnings ANTS6-0Months3T lh INFO: assuming .mgz format verbose mode on (medium mode): printing warnings reading input surface /usr/local/freesurfer/subjects/ANTS6-0Months3T/work/ANTS6-0Months3T/surf/lh.orig...

Any idea what in the data file could cause the assert "vt->nsizeMax > 0" to be triggered? Any idea how to go around it?
Thank you,
Christian
