Set valence from coordinates

Hallo,


Can standardizer set, check, correct the valence from coordinates? I.e. in the attached example (sdf) one bond order in the aromatic system is incorrect and needs to be corrected; the only information are the coordinates. And in case of the pdb there are only coordinates.  Bond orders should be determined using distances and angles.


Thanks,


Stephan

Thank you for reporting this issue, we could reproduce it and will fix it probably in the next major version.


Regarding Standardizer, it cannot fix these kinds of errors at the moment, though we are working on a fine structure checker framework that will be integrated in a future version of Standardizer. I can imagine a checker for this kind of error, but I am afraid, that it will not be among the first ones we will develop.

Thank you!  This error was not introdcued by any ChemAxon tool; I was just wondering if Standardizer can fix it; I have one solution, but it is not optimal.


Thanks,


Stephan
