Hello all,
I've been testing the Python module from rdkit.Chem import RegistrationHash for
some time now and I would like to use it in Java too. I browsed the RDKit
repository but I could not find it implemented in C++, and therefore, not
available in the Java JARs.
Am I missing it from somewhere
Hello RDKit community,
I normally do not use this channel to promote my own research, however, I
thought it was a good idea to share a piece of my work with you this time.
Myself and a colleague recently published a paper on calculating
hydrogen-bond strengths and free energy of hydrations from c
Hello all,
I have come across an unexpected behaviour by RDKit when reading MOL blocks
of the same compound in V2000 and V3000 formats. In particular, RDKit seems
to perceive the stereochemistry of the compound differently depending on
the format.
The original compound is a V3000 tab:

Hi all,
Anyone can help with this matter?
Thanks,

Hi all,
I have come across an issue while embedding structures with stereochemistry
configurations that presumably lead to clashes between atoms:
from rdkit import Chem
from rdkit.Chem import AllChem
smiles="C1N[C@@H]2CO[C@H]1C2"
m = Chem.MolFromSmiles(smiles)
mh = Chem.AddHs(m)
print(AllChem.Em

Hi all,
I am using rdkit_pypi==2021.9.4 to generate visualisation of compounds with
their atomic hydrogen bond strengths. In particular, I am using this
function to produce an SVG string:
d2d = rdMolDraw2D.MolDraw2DSVG(fig_size[0], fig_size[1])
d2d.drawOptions().annotationFontScale = 0.7
lStandardize import rdMolStandardize

Hi all again,
I wonder whether there is a way in RDKit to neutralise the charges of
compounds such as "[C+]1C2C2CC2C12". Specifically, in my case I am
dealing with only carbon sequences.
Thanks,

Hi all,
I am writing a function that removes atoms with only one bond and can be
applied recursively in order to find the scaffold of a molecule. The
function works in most cases but I have observed that, when aromatic rings
are involved, it produces a loss of information. This is an example:

Hi all,
I am using RDKit to set calculated values to atoms as shown below and I
would like to know whether it is possible or not to change the font size to
make it slightly bigger.

atom.SetProp("atomNote", str(atom.GetIdx()+1

Hi all,
Quick question: I have noticed that when I read a compound from an SDF/Mol
file where all coordinates are already defined, the embedding process
changes the conformation of the RDKit mol object, hence coordinates are not
preserved:
import rdkit
cdk2_path = os.path.join(data_path, "cdk2_va
mol.RemoveBond(bidx, eidx)

Hi all,
I have been working on a library that computes properties for molecules
where hydrogens are explicit. These properties are then saved into a
dictionary where keys are indices, then I am using the dictionary to depict
these properties on their corresponding hydrogens - also according to som
I have a question for the RDKit community that regards count-based RDKit
fingerprints. During a test, I have noticed that the compound *C1C1 has
a similarity (Euclidean) different than 1 against either [H]C1C1
or C1C1. So, I am wondering, how does RDKit encode starred atoms? I
