Fig 3. Spatial correlation between loci displacements.

(A) Spatial correlation of loci displacements $C_s^{\Delta t}\left(r\right)$ (Eq 4) with varying lag time (Δt). (B) Correlation length $l_c(={\int }_0^{\infty }[C_s^{\Delta t}\left(r\right)/C_s^{\Delta t}\left(a\right)]dr)$ as a function of Δt. Visualized on 3D chromosome structure are the displacement correlations of chromatin loci probed at short and large time gap (Δt = τ_BD and 10³ τ_BD) projected onto the xy-plane. The color-code on the structures depicts the azimuthal angle of loci displacement. (C) The displacement vector of loci in the equator plane are color-coded by direction. In each panel, the displacement vectors $\Delta \overrightarrow{r}(t=0;\Delta t)$ are calculated for Δt = 1, 100, 1000 τ_BD. Direction-dependent color scheme is depicted on the right.
