Dear FreeSurfers, I have data has been recon-all analyzed. I would like to compare the symmetry of function/structure property between LH and RH, such as cortical thickness. I already know that the vertices in the left hemisphere are not correspond to vertices in the right hemisphere. I would like to know the exactly symmetric vertex for both hemisphere. Thus the question is, how can I register both hemisphere to one hemisphere of fsaverage_sym, then compare them?
I followed the instruction: xhemireg --s sub001 surfreg --s sub001--t fsaverage_sym --lh surfreg --s sub001/xhemi --t fsaverage_sym --lh --xhemi then here is the error: MRISread(/data/sub001/xhemi/xhemi/surf/lh.sphere): could not open file No such file or directory mris_register: could not read surface file /data/sub001/xhemi/xhemi/surf/lh.sphere No such file or directory Thank you in advance for any suggestion! Regards, Ting
