Figure 1

An example β -sheet with its corresponding β -graph, β -matrix, and β -residue motif. Here we show an example conversion of a β-sheet (a) to its graph representation (or “β-graph”) (b) and the β-matrix projection (c). A β-residue motif (d) is a sub-matrix of its source β-matrix, or a connected subgraph of its source β-graph. The source code to perform these conversions are available for download (see Availability).
