Dear all,

Is it possible that the --projfrac-max has a bug (at least when used with mris_preproc)?

I sampled the same volume using --projfrac 0.5 and --projfrac-max (see below) and, when I overimposed the two surfaces, I noticed that in some vertices the first surface (i.e., 0.5) appear to have a higher value than the second (i.e., max).

Thanks! Marco
