Thank you for the response.
Just to clarify, when you say as long as the surface reconstruction is
correct do you mean that the surface should not have any gross defects and
surfaces such as the pial surface show correct wm/gm boundaries?

This is a surface-based atlas, so it is not sensitive to field strength
as long as the surface reconstruction is correct because surfaces align
with curvature and not intensity

Hello,
I wanted to extract brain morphometry data (cortical thickness,
surface areas, volume, etc) using PALS-B12 atlas. I have some 3T MRI
images that I have preprocessed using Freesurfer 3T flag.
I am wondering if it would be ok to extract MRI data from 3T images on
atlases such as PALS-B12. How do we know whether certain atlases are
insensitive to field strength?
Best,
Julia Shin
