Ambiguity of maximum common subgraphs. The bold black lines highlight the MCS between product and reactant molecule. The MCS has two distinct isomorphisms in the reactant. The alignment in the first row creates one fragment, and the isomorphic alignment in the second row causes three fragments. Dotted lines indicate the broken bonds resulting from the product alignment. The fragments visualize the remaining structure after subtracting the MCS from the reactant graph
