Synopsis
		sfmvo < in.rsf > out.rsf opt=y log=y mvo=y f=0.08 nnw=1600 n=1

Parameters
		float f=0.08 calculate frequency   bool log=y [y/n] if y, calculate logarithm of MVO   bool mvo=y [y/n] if y, MVO curve; otherwise, PVO curve   int n=1 number of window period   int nnw=1600 sample window   bool opt=y [y/n] if y, determine optimal size for efficiency
