Hi Michal, Though the RDKit theoretically has many of the infrastructure pieces required to handle organometallics (though there's not a lot you can do with them once you've loaded them), the difficult part almost always ends up being finding input files that have reasonably machine-readable

Hi Greg, Thanks for your fast reply. I've got two examples of ferrocene MOLfiles, generated by MarvinSketch in KNIME, from ferrocene.cdxml (found somewhere in the rdkit github repo), the other one from the ferrocene template in Marvin. But actually they are almost the same. The third example is

I would suggest that all coordination bonds to metal that exceed the accepted valence of an atom could be mark as zero-ordered. This is what happens in recent PDB reader changes and fixed a lot of problems with sanitization. Pozdrawiam, | Best regards, Maciek Wójcikowski

[Rdkit-discuss] Fingerprints standardization and cleaning

2018-09-13 Thread Mario Lovrić
