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.
In my lab we generally process ?h.thickness files with the next two commands before statistically analysis:
"mris_thickness -max 10 subjid ?h thickness_max10" "recon-all -qcache -measure thickness_max10 -target fsaverage_510 -fwhm 10 -no-isrunning -s subjid -hemi ?h"
To keep with this protocol, my questions are
- how do I use "mris_thickness" properly so that I don't overwrite
the files registered to fsaverage_510?
I think it will recreate the basic ?h.thickness file and will not touch registrations.
- in "recon-all -qcache", will it do the trick by substituting
"fsaverage_sym" for "fsaverage_510"?
Yes, that should work.
Thank you in advance, Cherry
