OK, thanks for the help.

 

And how do I use :

 

ILigand [] ligands = CIPTool.order(chirality.getLigands());

 

I need a way to get an array of the ligand atoms, ordered according to CIP.

 

Since ITetrahedralChirality can't return an array of ILigand anymore, I
can't fill in that array as a parameter in CIP.order(.) .

 

Regards,

Nick

org.openscience.cdk.geometry.cip.LigancyFourChirality

 

Didn't write the API so can't comment on why but I think you probably want
the ITetrahedralChirality. Stereochemistry in the CDK is a bit of a mess
(currently) but TetrahedralChirality is how stuff should be stored. Note
InChI currently loads 'AtomParity' class which is basically exactly the
same. SMILES will load ITetrahedralChirality though.

 

IAtomContainer        container = .

ITetrahedralChirality tc            = new TetrahedralChirality();

 

CIPTool.getCIPChirality(container, tc);

Hi,

 

I'd like to use org.openscience.cdk.geometry.cip.LigancyFourChirality as in:

 

LigancyFourChirality chirality = CIPTool.defineLigancyFourChirality(

mol, 0, 1, 2, 3, 4, stereo);

 

Why is that class protected? What should I use instead? The tests of
org.openscience.cdk.geometry.cip all use that class too, so I don't see why
that class should be protected.

 

Regards,

Nick
