To determine the potential of using SMILES correction for the expansion of the nearby chemical space, errors were introduced into known ligands using the previously described error introduction method and corrected using the SMILES corrector. As a starting point, compounds from the Papyrus set that are selective for AURKB were used. First, a random error was introduced into the SMILES sequences of these molecules and this was repeated 1000 times, after which duplicate sequences were removed.
