What is your mris_preproc command line? If you run mris_preproc with
--xhemi, it should give you two frames (left hemi and right hemi). If
you want to compute left-right, then add --paired-diff to the command
line. The output will be on the lh of fsaverage_sym. This can be
displayed on the white, pial, or inflated of fsaverage_sym. You can use
mris_apply_reg to map this back to the subject's native surface if you
want to display it there.

Hello,
sorry for asking this again
I want to calculate the difference between the thickness of one
subjects different hemispheres and show this on pial (left or right or
even fsaverage_sys). so I have ran :
surfreg --s $subject --t fsaverage_sym --lh
surfreg --s $subject --t fsaverage_sym --lh --xhemi
for my one subject. now I have two .reg files:
shahi/xhemi/surf/lh.fsaverage_sym.sphere.reg
shahi/surf/lh.fsaverage_sym.sphere.reg
If I am understanding this right, these two are the transform matrix
for both hemisphere of my one subject to fsaverage_sym (*right?*)
if I run mris_preproc with xhemi option I will get a vector which have
the length equal to number of vertexes. it's values are left-right
(*or right-left?*). how can I convert this vector to pial or inflated
surface? and how can I use lh.fsaverage_sym.sphere.reg to register my
pial directly to fsaverage_sym?
Regards,
Ashkan
