hi yczhang, see also my reply on Dec 2 2008 to frederic.anders...@univ-tours.fr re similar question -- search freesurfer archives on "comparing hemispheres" Ultimately to look at the symmetry question properly, we will need Doug's tool. In the interim, below is one, admittedly imperfect approa

no, the vertex index is essentially arbitrary and you can't use it to compare left and right. Doug had some tools for this, but I'm not sure whether they are ready for primetime yet. cheers, Bruce On Sun, 18 Jan 2009, Zhangyuanchao wrote: Dear Expert,   I want to exame the symmetry property

Dear Expert,   I want to exame the symmetry property of two hemispheres,for example, symmetry of cortical thickness or lgi,  I want to know whether the same ID of the two hemispheres after resampling using the average pial surface corespond to the same anatomical region.       For example,   ID

Dear Mr or Ms,   I want to see the symmetry property of two hemispheres,for example, symmetry of cortical thickness or lgi,  I want to know whether the same ID of the two hemispheres after resampling using the average pial surface corespond to the same anatomical region.   Thanks a lot!   yczhan
