Dear group,
I am new to FS and the ADNI protocol, thus my question: is it ok to have a slice thickness of 1.2 mm and in-plane resolution of 1.05 mm for cortical segmentation and brain volume analyses? This seems to be a sequence suggested on the FreeSurferWiki (I am using a GE750 3T).
Doesn't the anisotropic resolution introduce a bias?
Thanks a lot!
