This tool derives an external potential energy function from experimental nucleosome positioning data by assuming that nucleosomes interact with DNA like a fluid of hard rods. This energy function can then be used to derive sequence-specific nucleosome formation preferences, while accounting for hard-core steric restriction by adjacent nucleosomes. This tool is a reimplementation of the algorithm described in (Locke et al. 2010).
