Supplementary data for the manuscript: Image2SMILES: Transformer-based Molecular Optical Recognition Engine

This is the supplementary data for the manuscript: Image2SMILES: Transformer-based Molecular Optical Recognition Engine

It contains pairs of image-string, generated from 1M SMILES strings. These strings were randomly chosen from PubChem database.
It was prepared using the code, published at https://github.com/syntelly/img2smiles_generator/

To unpack do:
tar xvf subset_1M.tar.xz && tar xvf subset_1M_dump.tar.gz && rm subset_1M_dump.tar.gz

You'll get the following data:

• subset_1M.smi - list of 1M source SMILES
• subset_1M_dump - directory with images          
• subset_1M_result.csv - list of pairs FGSMILES - pathcode, first 3 chars of pathcode are corresponding subdirs in subset_1M_dump
• subset_1M_fails.csv - list of failed molecules from subset_1M.smi
• subset_1M_grpcounter.lst - list of counted groups, used in this generation

You can generate your own data using https://github.com/syntelly/img2smiles_generator/
