Dear freesurfer-team,

in my current studies, I am using the make_average_subject function to generate a group template of 14 subjects. I am doing TMS motor studies, so I am primarily interested in the region around M1. Independent on the number of subjects, I experience a meshing issue right on the gyral crown of the hand knob. There are 2-3 very large triangles. I attached an example image to this mail. I also saw this issue in the average brain you shipped with the software. Do you have any idea how I can fix that? I would be very grateful, if you could help me in this concern. The same problem occured when I generated the average template for only 3 of the 14 subjects. (freesurfer version 6.0.0)

Thank you very much and best regards!

Konstantin
