Hi, Perhaps I’m missing something obvious, but is there a way to calculate the number of aromatic atoms in a molecule? Cheers Chris ___ Rdkit-discuss mailing list Rdkit-discuss@lists.sourceforge.net

Re: [Rdkit-discuss] Query about creating SMILES string of small chemical fragment

Hi, Are these not intended to be query strings so rather than SMILES they should be regarded as SMARTS? If so you can perhaps just use a text editor to do a find and replace using schema shown here https://www.daylight.com/dayhtml/doc/theory/theory.smarts.html

Hi, I've been looking at ways to produce interactive plots within a Jupyter notebook and after trying a couple of options I used Plotly. This seems fairly straight-forward to use and I can produce interactive data frames, in addition to 2D and 3D scatterplots.
