Figure 3.

Interaction score per nucleosome ε as a function of the linker length ℓ. The vertical gray lines denote linker lengths equal to an integral number of helical repeats. The red dots (for ℓ = 30 bp and 60 bp) correspond to values deduced from single-molecule experiments in [11] (note that these measurement were performed at a different salt concentration from that used in the simulations).
