Hi Jeremy,
iirc you have to write mol = Chem.AddHs(mol).
In your code you are not keeping the object with the added Hs so there are
no explicit Hs to find when you iterate.
Cheers,

Hi everyone,
We are currently looking for a chemoinformatician/computational chemist at
insitro in my group, Computational Drug Design within the Drug discovery
department. We are considering candidates at various levels and also entry
level after a PhD or Masters. See more details here:

Hi all,
I initially wrote an fmoc smarts reaction to deprotect molecules as the
following:
reaction_smarts='[#7:1]C(=O)OCC1c2c2-c3c13>>[#7:1]'
Here's an example where this fails:
from rdkit import Chem
from rdkit.Chem import AllChem
mol=Chem.MolFromSmiles('O=C(O)COC1(Cc2cc[nH]n2)CN(C(=O
Hi Ling,
The initial smiles you wrote represents radical carbons with 3 unpaired
valence electrons each as they don't have hydrogens and hence even after
removing the isotope information, the smiles reflect this. I believe you
wanted to write ethane with isotope 13 carbons: '[13CH3][13CH3]'. Your
Hi Francois,
not sure if you have solved this yet. I believe it won't be possible to use
AllChem.ReplaceSubstructs without breaking the rings or enumerating them.
You can however use reactions for this problem. Here's an example based on
yours:
mol = Chem.MolFromSmiles('O=c1[nH]1')
rxn = AllC

Hi Mark,
it's best to add the hydrogens first and then set your coordinates:
m=Chem.MolFromSmiles('Nc1nnc2n1CCS2')
m2=rdmolops.AddHs(m, False, True);
Chem.rdCoordGen.AddCoords(m2)
Best,

Hi everyone,
I am cleaning up molecules to import into our database and canonicalizing
the tautomer using rdkit in python. Some cases result in a time-out and do
not go into my except to be caught. I would like to try setting the
maxTautomer to lower than 1000. I found there was no direct option t
Hello Mike,
you could create a function with your if else structure and use apply on
the pandas dataframe. For example, if you have a SMILES column in your df:
def addMol(smiles):
if Chem.MolFromSmiles(smiles) is None:
Etc
return None # or whatever you wish
Hi everyone,
I tried to virtually deprotect molecules using
the AllChem.ReplaceSubstructs() function. Stereochemistry of adjacent atoms
gets inverted in ChiralTag but not in _CIPCode. This gives me the wrong
output SMILES:
from rdkit import Chem
from rdkit.Chem import AllChem
from rdkit.Chem.Draw
