|| -dt f || set dt to f (default=1e-6) ||
|| -tol f || set tol to f (default=1e-5) ||
|| -conform || interpolate volume to be isotropic 1mm^3 (this option is on by default)||
|| -noconform || inhibit isotropic volume interpolation ||
|| -reduce n || reduce input images n (default=2) times ||
|| -sinc n || using sinc interpolation with windowwidth of 2*n (default=3) ||
|| -trilinear || use trilinear interpolation ||
|| -window || apply hanning window to volumes ||
