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
