Hi Rouhi
it's hard to tell from looking at the sphere.reg by itself. In general
though if the parcellations are correct then the registration must be
pretty good.

Dear Bruce
I checked the parcellation and look quiet OK. I attached two subjects , whcih
subj_1 shows bad registration to fsaverage and subj_2 shows the
good registration. I attached a file which compare two subjects according to
sphere and sphere.reg. For the subj_1 , it has more figures to see
how the parcellation is.
Thanks in advance

Dear Bruce
I am working on Freesurfer 2 caret meshes. I am using
FreeSurfer2CaretConvertAndRegisterClean.sh from Van Essen lab to create
caret surfaces. when I look at my subjects'
surfaces I can see in flat map in caret some of subjects sulci patterns
are really distorted and I think it is related to
sphere registration to fsaverage sphere. Beacsue
the code is using sphere.reg to create all surfaces. for the subjects
which I have less distortion on sulci pattern I have good
data (3 subjects) but for the (9 subjects)
rest it seems they have problem to register to fsaverage. Is there any
way that I can be sure that
sphere.reg properly created?
Thank you very much

how I can register the subjects surfaces to fsaverage surfaces? --
