In addition to 1D histograms, analyze_foldamers contains a tool for plotting Ramachandran-like 2D histograms of backbone pseudotorsion angle and backbone bondbending angle, similar to the Ramachandran plots Tozzini and coworkers mapped from the atomistic φ/ψ angles to the coarse-grained α-θ space. 36 2D histograms of any combination of two bonded parameters can also be generated in analyze_foldamers to investigate correlations amongst them throughout the folding transition.
