Hi freesurfites,
The mri folder of the fsaverage subject contains the segmenation files, such as aparc+aseg.mgz, etc. and in the surf folder there the corresponding surface files (?h.pial. ?h.white, etc). Question: which T1 data was used for these segmentations?
Cheers, Ed
Hi Ed
a combination of them (e.g. norm.mgz is used for the aseg.mz, but brain.finalsurfs.mgz for the white/pial)

Hi Bruce,
I cannot find these files in the subjects->fsaverage folder (version v5.1.0).

oh, sorry Ed, I missed that part of your question. fsaverage is a special case. The surfaces don't correspond to any volume and really shouldn't be used for anything except visualization. The asegs and aparcs I think are generated by majority voting across subjects in the spherical and talairach.m3z coordinate systems.

They were generated from the asegs of the input 40 subjects. They should not be used for much, certainly only for visualization purposes. doug
