Hi Sofia,

Another user seems to be experiencing a similar issue right now. How many subjects are you trying to average? I haven’t been able to replicate this, so it might require uploading some subjects. Can you send the make_average_volume.log?

best, Andrew

Hello,

when using "make_average_subject" in Freesurfer 6, we have noted that the medial wall label only contains 1 vertex leading, after applying "mri_glmfit, to significant results in regions of the medial wall. This problem didn't appear in Fresurfer 5.3

Is there something different with the command "make_average_subject" in Freesurfer 6 that prevent to correctly mask the cortical surface? We would like to include only cortical vertices in our analysis.

Thank you in advance.

Best, Sofia
