hmmm, this looks like a bug we've been chasing down that results in more
distortion than we used to have in the spherical registration.

Dear Bruce,
Thanks for replying. Yes the sphere.reg is warped. I send you two images
(the sphere and the sphere.reg of a subject), can you please let me know
your opinion about them?
Is this a normal result? What does exactly mean?
Thanks
Valentina

Subject: Re: [Freesurfer] spherical morphometry
what does not looking very good mean? The ?h.sphere is the metrically
optimal spherical representation, the ?h.sphere.reg is that sphere
warped
to be in register with the atlas (so it will always be more distorted
than
the ?h.sphere)

Hi,
I have two questions about the spherical morphometry:
Is the "rh.lh.sphere.reg" of each subject the sphere of the subject
registered on an average spherical cortical surface provided by
Freesurfer?
If the "lh.sphere" of a subject is good but his "lh.sphere.reg"
doesn't
look very good, what does it means?
Thanks
Valentina
