On the parent page, I discussed how to load PDB files, calculate phi/psi angles (ϕ,ψ), and thus generate Ramachandran Plots (see references).Now you don't have to use python to do this If you want to double check the results from python (see calculating the angles), you could use the EMBOSS program psiphi, or Wolfgang Kabsch and Chris Sander's DSSP.
Draws a Ramachandran plot based on the input PDB file (e.g. 1MBN.pdb). Makes use of a Gaussian KDE (kernel density estimation) to plot the density of favoured torsion angles (φ and ψ). Installation. RamachanDraw is hosted on PyPi. pip install RamachanDraw Usage. RamachanDraw includes useful functions to effortlessly draw a Ramachandran plot.
Ramachandran plot. Introduction This server will display a Ramachandran plot, against a background of phi-psi probabilities. Methods This server will display a coloured Ramachandran plot. Blue means helix, red means strand and green means turn and loop according to DSSP. The lines in the plot indicate prefered areas. The Ramachandran plot ([psi] against [phi]) is a useful way of assessing the stereochemical quality of a protein structure.
1. Ramachandran plot Description. The Ramachandran plot shows the phi-psi torsion angles for all residues in the ensemble (except those at the chain termini). Glycine residues are separately identified by triangles as these are not restricted to the regions of the plot appropriate to the other sidechain types.
Adding the values of three other sheet segments more clearly defines the area in which values for twisted sheets are located.
The Ramachandran plot ([psi] against [phi]) is a useful way of assessing the stereochemical quality of a protein structure. If the structure is well refined, the [psi]-[phi] plot should have
The Ramachandran Plot Explorer is designed to make it easy to examine the conformation of a polypeptide - through the interactive Ramachandran plot (φ-ψ angles) and χ-angle tool. Simply click on a residue, then drag the marker on the Ramachandran plot.
Apr 28, 2007 A selection of programs to generate and display Ramachandran (phi/psi) plots for proteins from PDB files.
Introduction This server will display a Ramachandran plot, against a background of phi-psi probabilities. Methods This server will display a coloured Ramachandran plot. Blue means helix, red means strand and green means turn and loop according to DSSP. The lines in the plot … The Ramachandran Plot Window plots only values for the currently selected amino-acids of the current layer.
It would be
Choose options Entire polypeptide chain Specify phi , psi limits: Choice of residues All residues Particular residue type
The Ramachandran plot shows the statistical distribution of the combinations of the backbone dihedral angles ϕ and ψ. In theory, the allowed regions of the Ramachandran plot show which values of the Phi/Psi angles are possible for an amino acid, X, in a ala-X-ala tripeptide (Ramachandran et al., 1963). 2017-12-22

It is however interactive. I only have here a Rama.(phi,psi) plot, but the code can be easily extended to other types of data. For instance, I had this working for an energy vs distance data that I had generated by another script.

ラマチャンドランプロット (Ramachandran plot) は、1963年に G・N・ラマチャンドラン （英語版） 、C. Ramakrishnan、V. Sasisekharanによって開発された、タンパク質構造中のアミノ酸残基の主鎖二面角φに対してエネルギー的に許容されるψの領域を可視化する手法である 。
Installation. RamachanDraw is hosted on PyPi. pip install RamachanDraw Usage. RamachanDraw includes useful functions to effortlessly draw a Ramachandran plot. The Ramachandran Plot Window plots only values for the currently selected amino-acids of the current layer. The name of the current layer is drawn at the bottom left of the window. Amino-acids appear as a little cross with the exception of Gly that appears as a square.
