Just a quick thing: I don't know if this is supposed to be a bug or a
feature, but I noticed that this seems to be cau

Hi Gustavo,
Chem.Atom.HasQuery() and Chem.Bond.HasQuery() return True when the
underlying atom (or bond) is an instance of Chem.QueryAtom (or Chem.
QueryBond).
Query atoms and bonds can either be defined through SMARTS expressions...
from rdkit import Chem
from rdkit.Chem import rdqueries
a = Ch
This works perfectly!
I could understand most of what you did there ;-), but what does the
".HasQuery()" mean? The RDKit API is not very clear about it: "Returns
whether or not the atom has an associated query". Is this described
anywhere else?
Thank you so much!

Hi Gustavo,
you should be able to address this with a custom AtomCompare (and
BondCompare, if you want to use bond queries too) class, that now is also
supported from Python.
You can take a look at Code/GraphMol/FMCS/Wrap/testFMCS.py for inspiration
how to use it; here's something that seems to wo

Alternatively, since your template is small, you can brute-force enumerate all
possible matching

Hi,
Thanks a lot for the reply! However, in this case, it looks like I would
have to somehow label the isotope in every query molecule, right? For
example:
```
template =
Chem.MolFromSmarts('[c]1(-[2S](=[3O])(=[3O])(-C)):[c]:[c]:[c]:[c]:[c]:1')
mol1 = Chem.MolFromSmiles('CS(=O)(=O)c1ccc(C2=C(c3ccc
Hi Gustavo,

Unless things have changed since I last looked at the algorithm, you can't
meaningfully pass a SMARTS-based query molecule into the MCS program, outside
of a few simple cases.
It generates a SMART
Hi all,,
I would appreciate some pointers on how it would be possible to find the
maximum common substructure of 2 molecules, where in the template structure
some atoms may be *any*, but some other atoms must be fixed.
Currently, I'm trying to use rdFMCS module. For example:
from rdkit import Ch
10 matches
