Despite many application examples for smiles, smiles has inherent limitations, including nonunique representations of the same molecule, potential for generating invalid structures, an absence of lattice information for periodic system and insufficient chemical context in individual tokens14,15,16,17. Smiles offers a concise and humanreadable format for representing chemical structures using text strings. Here the authors present tsmiles, a representation that encodes molecular substructures into strings, giving more structure to the smiles representation. In this article, we propose the rootaligned smiles rsmiles, which specifies a tightly aligned onetoone mapping between the product and the reactant.
