Hi Carolina, I think we gave some details about the method here:
H.D. Rosas, S.Y. Leea, A.C. Bendera, A.K. Zaletaa, M. Vangelc, P. Yu, et al, Altered white matter microstructure in the corpus callosum in Huntington's disease: Implications for cortical "disconnection", Neuroimage, 49(4):2995-3004, 2010. essentially we find the callosum as the set of white matter in which left and right hemi white matter are adjacent. We then separate it into segments along it's primary eigen-axis (which is mostly A-P). Note that we also correct the segmentation for the orientation of the midsagittal plane cheers Bruce On Sun, 2 Oct 2011, carolina.mr wrote: > > Hi, > > How is the segmentation of the corpus callosum is done?
