[Rdkit-discuss] fingerprint C++ sample code

2012-04-12 Thread Gonzalo Colmenarejo-Sanchez
Hi,
Does anyone have a Daylight-like fingerprint example C++ source code that would 
be willing to share?
Thanks,

The RDKit function RDKFingerprintMol() can be used to generate a
fingerprint that is, I believe, similar to the Daylight fingerprint.
By default the function includes branched subgraphs instead of just
linear paths, you can get closer to the Daylight fingerprint by
calling RDKFingerprintMol with the branchedPaths argument set to
false.

The source is here, starting at line 110:
http://rdkit.svn.sourceforge.net/viewvc/rdkit/trunk/Code/GraphMol/Fingerprints/Fingerprints.cpp?revision=2017view=markup

Note: there's a lot of room for improvement in how the paths are
hashed to actually set fingerprint bits.

[Rdkit-discuss] un-oneandahalfs

2012-04-12 Thread Paul Emsley

Hi all,

(Sorry for another noob question)

When creating a 2d depiction, or otherwise, is there a way to turn a 
carboxylate (with ONEANDAHALF bonds between the carbon and oxygens) into 
something with a carbonyl oxygen (DOUBLE) and a hydroxyl oxygen (SINGLE)?

Cheers,

Paul.
