Question about chirality and model results from paper

[kosonocky]

Hi,

ChemBERTa was trained on achiral canonicalized molecules, as evidenced by the achiral canonicalized dataset.

The MoleculeNet fine-tuning datasets in the paper contain chiral molecules. How was this addressed?

Did you canonicalize the chiral molecules to make them achiral canonicalized? What about duplicates? (since there are stereoisomers)

Or, did you just inference on the chiral strings? This would certainly cause some problems.

I didn't see any mention of this in the paper.

Please let me know, Clay
