Re: [Rdkit-discuss] missing MolFromSmiles error output in Jupyter

I would expect to see a "SyntaxError: invalid character in identifier" as Python doesn't recognize left-handed or right-handed double quotes in a way that doesn't cause an error. Instead, the MolFromSmiles() appears to be evaluated. Is that a c++ method (hint, hint)?

Hope that you'll find out > a good library of SQL OR mapper for python. SQLalchemy creates a fairly specific ecosystem that you have to buy into for it to make sense. When you don't have objects, only a table of properties, OR mapper is just bloat. With parallel processing your bottleneck is going to be database inserts. One option is write out CSV file(s) from each thread/job, concatenate them in the final node, and then bulk-import into the database: typically CSV (or other such format) bulk import is orders of magnitude faster than inserting one SQL statement at a time. -- Dmitri Maziuk ___ Rdkit-discuss mailing list Rdkit-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/rdkit-discuss

You could try generating multiple conformers instead and checking if one of them returns EQUAL. -- Dmitri Maziuk ___ Rdkit-discuss mailing list Rdkit-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/rdkit-discuss

NaNs are great because you can tell "invalid result" from 0, or some other number that's perfectly valid per se, just out of bounds in your particular corner case. -- Dmitri Maziuk ___ Rdkit-discuss mailing list Rdkit-discuss@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/rdkit-discuss

Re: [Rdkit-discuss] PDBBlock file
On 7/5/2018 1:39 PM, Paolo Tosco wrote: As the PDB format includes no stereochemistry, no coordinates are needed, and by default they are zero, as the molecule does not have a conformation yet. Hmm. One could argue that PDB format *is* 3D coordinates, so a block with all zeroes is quite pointless. And of course counter-intuitive.
