Ramachandran-plot data (phi vs psi protein backbone torsion angles) for all 116,789 Glycine residues in a quality-filtered dataset from 8000 protein chains.  Glycine populates the 180°,180° phi,psi region, so that the standard Ramachandran plot with 180*,180° at the corners splits up the continuous regions.  This "redux" plot shifts phi by 180° and psi by -90° to make the populated regions continuous, which puts alpha-helix in the lower right and extended conformations across the top.   At 3600x3600 pixels, each pixel represents the data in a 0.1° bin, color-coded as gray: 1 datapoint, orange: 2, gold: 3, yellow: 4, yellowtint: 5, white: 6.
