Fourier syntheses corresponding to the test model. (a) The synthesis calculated with all 52 low-resolution reflections of the 60 Å resolution zone reveals the expected number of globular components. An exhaustive phase search is impossible owing to too large a number of phase combinations (more then 1024). (b) The synthesis calculated with 11 strongest low-resolution reflections of the 60 Å resolution zone. Here, the envelopes are merged and envelope-based searches will fail to find the correct solution.
