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

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
