Do you have a group of subjects that you want to use as an average? If so, you can just map all their thickness maps to your patient subject with mris_preproc --target patientsubjectname [then usual arguments] Compute the mean with mri_concat outputofmris_preproc.mgz --mean --o groupmean.mgz Yo

Hi Tim if you upload the input files to mri_deface and the full command line I'll take a look. Is this the dev version you are using? cheers Bruce On Mon, 3 Feb 2020, Tim Schäfer wrote: External Email - Use Caution Dear FreeSurfer experts, I am running mri_deface for all relevant
