Figure 4.

Surface plots of the combined score of dimer models generated using the X-axis of the PEG alignment tensor (A), the phage alignment tensor (B), and the consensus orientation (C) as the symmetry axis. During the search, the center of mass of one subunit is fixed at the point (35 Å, 35 Å). The translation refers to the coordinate of the center of mass of the second subunit. Models with VDW energy higher than the median value or RDC correlation <0.85 or residual pairing score <0 are given a score of 0. The score is indicated by the color of each grid point: (black) 0, (yellow) 1. The color gradient for the score is also shown on the right of each plot.
