Hi,

we don't in general use the aseg.mgz for cortical stuff, so if it look inaccurate, but the ?h.white and ?h.pial surfaces look accurate then I wouldn't worry about it. It's hard to diagnoe without any images though.

cheers, Bruce

Dear freesurfer experts, I got uncorrected segmentation results, especially occipital cortex, from brain of age 8-13. I found similar problem in adult brain in freesurfer mailing list and the resolving answer like below. "use the control points with the mri_ca_normalize flag as part of the aseg. I've not used the command much, but you should be able to add the flag '-f tmp/control.dat' to the normal mri_ca_normalize command to run this step"

Do I have to do any procedure for brain of age 8-13 in addition to suggestion like above?

Thanks,
