Webb23 mars 2024 · Canonical SMILES is a unique way of writing a SMILES for a molecule, where some rules about numbering defines the ordering of the atoms. This ensures that there is only one unique SMILES corresponding to one unique molecule. It is often useful to have this 1:1 correspondence. WebbA new representation system that is capable of handling the stochastic nature of polymers and based on the popular “simplified molecular-input line-entry system” (SMILES) is …

WebbThere are 7372 polymers in total in the current database. The respective Tg count distribution is presented in Figure2a. As mentioned previously, the SMILES strings of polymer repeat units are employed for polymer representation. Note, however, that the general SMILES string may not be unique for molecular representation. For example,

WebbThe dc.feat.BasicSmilesTokenizer module uses a regex tokenization pattern to tokenise SMILES strings. The regex is developed by Schwaller et. al. The tokenizer is to be used on SMILES in cases where the user wishes to not rely on the transformers API.
