I concur. I have seen similar results in primary visual cortex from ~40 subjects. While fs 5.1 estimated mean thickness in the range of 1.5 to 1.9 in V1, fs 5.2 is giving me V1 thickness in the range of 2 to 2.3.

Previously, the mean thickness is 2.24 mm in 5.1.0; now it is 3.28 mm in 5.2.0. They are significantly different, t(160) = 56.71. The correlation between the two versions is r = .33 Is this something possible?? I can't see what went wrong in my procedures. Thanks!
