Hello FreeSurfers, I would like to run a group analysis on cortical thickness using existing Desikan labels.
When I run the command for smoothing, should I replace *--cortex* with *--label-trg*? In other words, for ROI analysis, should we smooth *only* the target mask? mri_surf2surf --hemi lh \ --s fsaverage \ --sval lh.gender_age.thickness.00.mgh \ --fwhm 10 \ * --cortex* \ --tval lh.gender_age.thickness.10B.mgh I followed the instructions from here: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI https://surfer.nmr.mgh.harvard.edu/fswiki/mri_glmfit http://freesurfer.net/fswiki/mri_surf2surf Thank you! Mihaela
