Hi freesurfer experts,
I'm investigating lh-to-rh asymmetry and am following instructions on this
page :http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi.
My question is, what does the "--xhemi" flag do in the "mris_preproc"
command? It seems to me that it calculates (lh-rh) value at each vertex for
lh-rh)/[(lh+rh)/2] rather than (lh-rh). Can I do that using mris_preproc
and how?
Thanks,
Cherry

Dear Freesurfer experts,
I'm trying to investigate lh-to-rh asymmetry, so I register my subjects to
the subject of fsaverage_sym following the instructions on this page:
http://surfer.nmr.mgh.harvard.edu/fswiki/Xhemi. After all the surfreg
commands I've got ?h.thickness files in subjid/xhemi/surf.
