Dear Freesurfer Staff, I encountered the following error while running tracula - longitudinal: ERROR: flag ; unrecognized The exact command line i ran is the following one: trac-all -prep -c '/home/elia/scripts/Tracula/LCL/dcmTimePoints_tar-2/tracula.config' I will attach the complete error log as well as my dmrirc file (which I called in this case tracula.config).
