Dear Christopher,

I just downloaded MCALT atlas and found that dorsal skull edge of the MCALT atlas images did not match the dorsal skull edge of MNI template included in SPM12 or WFU pick atlas.
i.e. Skull of [X, Y] = [0, 0]mm in MCALT atlas is 77mm (in Z axis), while the point in MNI is located 92mm in Z axis.
(attached image derived from SPM's "Check Reg")

I was wondering if there is anything worng with my files or MCALT atlas files.
Thanks for your help!

Best,
Yosuke
