External Email - Use Caution 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 how to go around it? Thank you, Christian
