Model spectrum graph and sequence graph for two adjacent residues Ω and Ψ. In the spectrum graph, vertices representing y and b ions are connected by four types of edges: arrow edges (Red arrows), forward-slash edges (Blue lines), backslash edges (Green lines), and vertical-bar edges (Purple lines). The spectrum graph is transformed to a sequence graph, where two vertices representing residues Ω and Ψ are connected by a traversable edge (Black solid line).
