Hi Tommi, to compute an average, all you need to do is run
mri_concat file1.mgh file2.mgh ... fileN.mgh --mean --o average.mgh

Dear Surfers,
I have (non-fMRI) .w format surface overlays/labels, computed at the
smoothwm surface in each individual subject, in 25 subjects. FS5.1
recon-all has been run for all T1 images.
I already managed to convert all individual surface overlays into the
surface space of one of the subjects (or fsaverage) using mri_surf2surf,
and in the process also converted the format from .w to .mgh (as I
understand .w is pretty much legacy).
Now, I would just need to compute an average across these overlays. I
would greatly appreciate any suggestions which FS tools to use for this.
Thank you in advance!
(In case it matters, the overlays are E-field estimates, with a numerical
value given for each vertex point. Also each overlay has only one time
point.)
Bests,
Tommi
