a Chord diagram of input PDB structure. The arch of the chord diagram shows the secondary structure labels by DSSP [12] (helix in red, coil in white, and strand in green). Chord widths and transparency correspond to the actual physical distances (smaller distances have larger widths and lesser transparency) and chord colors are based on the residue index number—red through green to blue. b The structure of the corresponding PDB file. c The heatmap diagram with the predicted contact map shown in the upper triangle with the PDB distance map in the lower triangle. The colors in the diagonal line of the heatmap show the DSSP assigned secondary structures (helix in red, coil in white, and strand in green). d Chord diagram of the predicted contact map; Chord widths correspond to the predicted contact confidence. The chord diagram (in d) and the heatmap (in c) clearly highlight the patterns such as strand-strand interaction
