Hi James,
If that's pulling the inchi zip from rdkit.org then the MD5 shouldn't have
changed.
The easiest thing is to just replace the MD5 in
$RDBASE/Code/cmake/Modules/FindInchi.cmake with what you're getting (after
making sure it is in fact the correct zip file of course).

For what it's worth, this one works too:
m.GetSubstructMatches(Chem.MolFromSmarts('P1->[Zr+3]<-C1'))
It looks like a problem in the way ring closure bonds are being handled in

Hi Emre,
Both of those compounds look like they have conflicting stereochemistry
information in the ring systems, i.e. the stereo which is specified cannot
actually exist. There's something else going on as well (that looks like a

If you're willing to live with the RDKit's definition of bridgehead (see

qa = rdqueries.IsBridgeheadQueryAtom()

I'm currently sending this announcement only to the mailing list so that
people here have a chance to register first. I'll do the usual social media
I first heard the term "para stereochemistry" from Salome Rieder (a PhD
student at the ETH Zurich), who pointed me to this paper as a source for
term:
https://pubs.acs.org/doi/pdf/10.1021/ci00016a003
I tend to call this "dependent stereochemistry" since I think it's clear,
but that's definitely

Hi James,
I don't think that's the same bug as #3490. I think it's something
different; "yay".
;-)
It would be great if you could file a github issue for this.
Thanks,

Hi Jean-Marc,
In that particular configuration:

the central atom is not a chiral center since atoms 1 and 5 have the same
absolute stereo.
However, if you change the stereo of either atom 1 or 5, then the central
atom can be a chiral center:

Hi,
This year's RDKit UGM is going to take place October 14 and 15. It will,
unfortunately, once again be a purely virtual event. Hopefully next year we
will be able to travel again and all get together in one physical location,
but this year it's not possible to really plan an in-person meeting.
Hi Gonzalo,
Yes, the RDKit uses the InChI trust library to handle InChIs.

Hi Francois,
The implementation which is there does, I believe, the right thing.
However... first you need to find the Murcko Scaffold, then you can convert
that scaffold to the generic form:
In [5]: m = Chem.MolFromSmiles('CCc1ccc(O)cc1C(=O)C1CC1')
In [6]: scaff =

What do you see when you execute this quick test to ensure that ipython and
the rdkit are both really installed?
python -c 'import IPython;import
rdkit;print(IPython.__file__,rdkit.__file__)'

Hi Andrés,
The typical reason for this problem is that you created a separate
environment for the RDKit and installed the package there, but forgot to
install ipython. When this happens ipython is run from the base environment
and can't find the rdkit. Can you please confirm that you have ipython
Hi Geoff,
Congrats to you and co-authors on the paper and thanks for offering to
contribute to the RDKit.
Given the dependence on py_rdl, this probably isn't currently a good match
for the core RDKit (we try to minimize adding additional external
dependencies), but it would be great to have it
