You can do the same thing with lh.area, but make sure to include --jac for jacobian correction.

Hi FreeSurfer Experts,
I am tryinig to extract area from a volume-defined ROI. I used code from the FreeSurfer websiite (https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness https://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness) to extract thickness, but I was not able to extract area. Here is my code for thickness:
mri_surf2surf --s ../../sub-004_session1 --trgsubject ../../fsaverage --hemi lh --sval lh.thickness --tval lh.thickness.fsaverage.mgh mri_segstats --seg $SUBJECTS_DIR/../../fsaverage/label/lh.fsaverage.MFGbin.mgh --in lh.thickness.fsaverage.mgh --sum segstats-lh.thickness.MFGbin.txt
How do I modify to extract area?
Thank you!
Jessica
