Re: [Freesurfer] Usage of --area option in estimating the vertex-wise maps of surface area

Hi Xi-Nian, As Doug said, they don't do the same thing. The method in the paper uses a different kind of interpolation to allows the preservation of the amount of area, whereas mris_preproc achieves the same globally using a Jacobian correction. The results aren't expected to be identical at the v

Hi Xi-Nian, it does not do the same thing, but it does something similar. Anderson found that it gave similar results in a lot of cases, but he has found some differences. If he's still following the FS list, maybe he can comment. doug On 5/11/13 9:53 PM, Xinian Zuo wrote: Hello Doug,

Hello Doug, I am doing some association studies between functional measures and surface area. In using mris_preproc, there is an option --area. Does this do sth similar to that as Winkler et al. (2012)? Winkler et al., 2012. Measureing and comparing brain cortical surfacearea and other areal qua
