[Freesurfer] averaging lh and rh thickness maps on fsaverage_sym surface

2013-05-14 Thread Subhabrata Chaudhury
Hi,

I want to create an average thickness map of lh and rh. I have run surfreg 
steps to map lh to lh sym and rh to rh sym. 

Can you advise what to do next to mke average thickness maps between two 
hemispheres ? 

Will either mris_calc or mri_average work to make the average map ?

Thank you 

Subha

Just run the next step, ie, mris_preproc but leave off the 
--paired-diff. Then run
mri_concat preproc.out.mgh --mean preproc.out.mean.mgh
