[Freesurfer] mirror labels across hemispheres

Hi, I am trying to map a label in the left hemisphere to the right hemisphere. To do so, I have registered the subject's native surfaces to the fsaverage_sym template using surfreg -s $subj -t fsaverage_sym -lh surfreg -s $subj -t fsaverage_sym -lh -xhemi What would be the best way to map the

[Freesurfer] creating 'Mid' surfaces

Dear FreeSurfer Experts, What is the best way of creating surfaces approximating layer IV of the cortex or the 'mid' surface (I.e. Surface between grey and white matter). Thank you very much for your help. Regards, Christine ___ Freesurfer mailing li

[Freesurfer] Downsampling pial surfaces and mapping output to fsaverage6

Dear FreeSurfer Experts, I would like to down-sample the pial surface of individual subjects to have the same number of vertices as fsaverage6. I have done so using: mri_surf2surf --hemi lh --srcsubject 'subjectID' --sval-xyz pial --trgsubject fsaverage6 --trgicoorder 6 --trgsurfval 'outputfile

[Freesurfer] surface area vs. areal expansion

Dear FreeSurfer experts, I would like to compare surface area in a vertex-by-vertex fashion across two subject groups. There has been some discussion already on the mailing list and it seems that areal expansion is a better measure than simply surface area for doing so. I also remember reading
