Extended Data Fig. 3: 3D variability analysis of FliD-FliC complex.

a, Projection of each variability modes. b, Scatter plots of reaction coordinate distribution of particles between adjacent pairs of components. c, Projection of variability mode 1 from x, y, z axis. d, The distribution of latent coordinates for the component in c. e, Histogram of clusters of latent coordinates. Clusters 10 to 2 represent the first flagellin being incorporated, while clusters 19 to 17 represent the second flagellin. f, Volume map that are reconstructed from clusters 12, 4, 15, 1 in e.
