Hello Freesurfer Team,
Would you be so kind to provide freesurfer steps to implement warping fsaverage mean thickness data on individual subject inflated brains ? I am using expert opts to disable cortical thickness restriction, and set mris_thickness -max 20 as I want to find fcd to cortical surfaces. The reason i need normalization is that there is zones like sulci orbitales have bigger thickness accross subjects group ( control ) and have red LUTs on inflated thickness map. So i would like to normalize thickness over control group, to use it on patients to exclude "normal" thickness excedings to include only increased FCD zones. The main issue I faced is how to warp fsaverage mean thickness data on individual subject's inflated brain as they have vertices number missmatch.
Steps I tried:
1) make_average_subject
2) mri_concat --mean to create mean thicknesses over group?
Thank you
