The scaffolding graph of the CALC BGC. (Left) Five solid edges in the scaffolding graph correspond to five contigs shown in Figure 4 (bottom) that contain A-domains. These contigs are shown as a red edge (A-domains 1, 2, 3, 4, and 5), a green edge (A-domain 6), a pink edge (A-domain 7), a blue edge (A-domains 8, 9, and 10), and a black edge (A-domain 11). Eight dashed edges in the scaffolding graph connect solid edges that contain closely located domains in the BGC subgraph. (Right) Two rural postman routes in the CALC scaffolding graph. The first tour contains all violet dashed edges and results in the (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11) arrangement of A-domains, while the second tour contains all brown dashed edges and results in the (1, 2, 3, 4, 5, 7, 6, 8, 9, 10, 11) arrangement of A-domains.
