Re: [Rdkit-discuss] RDKit-fingerprints set all bits for complex molecules?

Hi, Did you try setting the length of the fingerprint (fpSize) to a higher value than the default 2048 to see if you can get one with 0's? Cheers, Bruce > > Message: 2 > Date: Thu, 1 Jun 2017 16:28:40 +0200 > From: Nils Weskamp > To: Rdkit-discuss@lists.sourceforge.net > Subject: [Rdkit-discus

Re: [Rdkit-discuss] EState fingerprints for differently protonated SMILES

Hi Greg, Thanks, that makes sense. I see the table has only charged/protonated atom types for nitrogen. Obvious once you look at it... ;) Cheers, Bruce On 16 May 2017 at 06:53, Greg Landrum wrote: > Hi Bruce, > > > > On Mon, May 15, 2017 at 3:46 PM, Bruce Milne wrote: >

[Rdkit-discuss] EState fingerprints for differently protonated SMILES

Hi, I've noticed that if I define a molecule as neutral, positive and negative (depending on protonation) the EState indices calculated by RDKit reflect the changes as expected: m = Chem.MolFromSmiles('CCO') m_neg = Chem.MolFromSmiles('CC[O-]') m_pos = Chem.MolFromSmiles('CC[OH2+]') EState indi
