Nothing wrong per se, it is just that the inflation was done assuming a certain number of vertices. You can try changing the number of iterations in the inflation with,eg, cd $SUBJECTS/fsaverage/surf mris_inflate -dist .01 -f .001 -no-save-sulc 5 lh.smoothwm lh.inflated In this case I set it to 5, but you can play with it.

If you don't need the inflated for this, then you can just ignore

Is there something wrong?

Dear Freesurfer team,

I created the FS average subject of the same dataset with 5th and 6th order icosahedron tesselation using the following commands: make_average_subject --fsgd fsgd.txt --ico 5 --out avg_subject_ico5 make_average_subject --fsgd fsgd.txt --ico 6 --out avg_subject_ico6

When I load the inflated surface of the avg_subject_ico5 with tksurfer , it has a oval shape while > when I load the avg_subject_ico6 it seems to be a normal shape. Please, see attached image.

Thank you in advance.

Best wishes, Marina.
