Improved separation using clustering of pairs of spikes with similar structures in mixtures of SIV mac239 and SIV CP-MAC. Individual sub-tomograms were paired and averaged in 3D based on the criterion of having the shortest Euclidean distance in the reduced dimensionality representation of the mixture following initial alignment. Lines and markers related to spike pairs originating from the SIVmac239 alone and the SIV CP-MAC alone are colored red and blue respectively. The overlap between the scatter-clouds of the pure SIVmac239 pairs and the pure SIV CP-MAC pairs is ~43%.
