This plugin reconstructs a 3D model of chromatin using ideal DNA interbasepair helical parameters (in proper r.h.s. ref. frame ordering)

The 3D curve is calculated using the DNA interbasepair helical parameters (in proper r.h.s. ref. frame ordering)

Gamma = (shift,slide,rise)
Omega = (roll,tilt,twist)
Default is 14 nucleosomes 146bp each.
and a 27bp length of straight linker

This plugin is useful for investigating the folding of chromatin based on the "two-angle" model where the total linker length and twist between nucleosomes determines the overall geometry of chromatin. It is a homogenous model of chromatin. An inhomogenous model can be obtained from http://dna.ccs.tulane.edu/vdna/.
