Application of the extended S-FFT phase refinement algorithm to intensities of TVAL calculated (a) with 50% randomly assigned negative scattering factors and (b) with all atomic scattering factors of one of the two symmetry-independent molecules made negative. Atoms with negative refined densities are depicted in grey. The peak search was performed on the Fourier map computed with the phases from the extended S-FFT.
