Hi FS Devs, Would it be possible to add an "append" flag for use with aparcstats2table and asegstats2table? If I understand their usage correctly, each time one of them are run they will create (or overwrite) a new file. Not urgent but would be useful. Thanks, Mitch

Dear FS Experts, When using --projfrac-max or --projfrac-avg, how is the “min” component defined? If I specify: --projfrac-max -2 1 0.1 Is the min (-2) simply 2x the thickness at each vertex below/inside the GM/WM boundary? Thanks in advance! Mitch
