Figure 3.
The average local RMSD of nucleotide doublets compared to libraries of various sizes. Orange circles represent the full set of 20,613 doublets, so that ⟨RMSD⟩ is the fit of all of the doublets of every nucleotide. Blue squares represent the reduced set of 8466, where the ⟨RMSD⟩ is to the best doublet for each nucleotide. We also show in red diamonds the ⟨RMSD⟩ to the second best doublet for each nucleotide. In the inset a base-10 logarithmic scale for library size, which also includes the library of size 20,613 with an ⟨RMSD⟩ = 0.0 Å as each fragment is in its own cluster.
