[Rdkit-discuss] SDMolSupplier warning 2023.9.2

[Mandar K. <man...@gm...>]

Hello,

I am using RDKit 2023.9.2's  SDMolSupplier to read docked SDF files (V2000
formats, suppl  = Chem.SDMolSupplier(sdf_file);) and getting a warning as:

Warning: molecule is tagged as 2D, but at least one Z coordinate is
not zero. Marking the mol as 3D.

I could not figure out how Rdkit is guessing it as 2D structure, as
there is no such information in SDF.

Is there any more information need to provide SDMolSupplier to make it
understand it's a 3D molecule?

I kindly look forward to hearing to suggestions.

TIhanks in advance,

Mandar Kulkarni
