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
