Scatter plots displaying the figure of merit LLG versus translation Z-score for partial solutions clustered by the values of the rotation angles in the case of TsaR, representative of the typical landscape occurring when phasing with predicted models. The correctness of the solutions is measured by average phase errors to the deposited structure and is represented in (a), (b) and (c) by the colour scale. The structure contains two copies in the asymmetric unit displaying different conformations, one closer than the other to the search model. (a) Rotation cluster containing numerous, well discriminated, correctly placed fragments. (b) Rotation cluster with incorrect and marginal solutions. (c) Rotation cluster with incorrect solutions. (d) Solutions from all clusters (in different colours) clearly set apart the orange cluster shown in (a).
