Hi Libby,
There's not currently anything directly available to do this, but some
pieces that might help are sort of there.
You could imagine getting drawings of the reactions as SVG and then adding
the arrows that indicate the mechanism to that.

Dear all,
I'm starting the uploads of the conda builds of the 2017.09.2 RDKit
release. These builds have been done using the "new" conda version (4.3.30)
and numpy v1.12.
The linux builds are available now, Windows builds will be there later this

Hi Nick,
When you import IPythonConsole it monkey patches the substructure function
so that it saves info about the results when you do a substructure search
on a molecule.
The data member is called __sssAtoms, and if you delete that you should no

This is happening because the code doesn't recognize 7 as a valid valence
state of As.
This is, as you note, inconsistent with how P is handled, which doesn't
make a lot of sense.
Fortunately, it's a fixable problem. :-)

At the moment the only way to do this is to disable the "cleanup"

consequence that things like the hypervalent N in nitro groups (i.e.
"-N(=O)=O") is not cleaned up.

Maybe we can try simplifying. What would you like to have returned for each

I'll fix it for the 2017.09.2 release.

Hi Maciek,
You can do this by calling setScale() method on MolDraw2D(). There's not a
decent python example around yet (would be something for the cookbook I
suppose), but the C++ code isn't too complex and demonstrates how it works:
quot;, but you likely want
to do params.adjustDegree=False.
it's worth being careful with makeBondsGeneric... there you could match
single against triple, which is unlikely to be you want.

This isn't a really straightforward one.
One solution (and I think the best one) is to change the aromaticity model
used to match whatever is generating the hits (in your case it's the Symyx
cartridge).
The RDKit has functionality to do this already when you call the
SetAromaticity() function:

Hi Tyler,
That's a perfectly reasonable request and it is something that you should
be able to do with the RDKit reaction handling code, but unfortunately it
is not currently possible.
This type of problem tends to not have a quick fix, but I will take a look
and see.

Hi Juuso,
A quick solution that seems like it would covert most cases would be to
construct a molecule from you input without doing sanitization, calculate
the atomic valences in non-strict mode, and then to identify all neutral N
atoms with a valence of 4 and add a positive charge to them
Hi Sai,
This recently came up somewhere else too. We may be able to change the
requirements for the conda package so that it supports more recent versions of
numpy too.
I will take a look over the next day or so and reply again on this thread with
an answer

The other answers on this thread have been right on point with the
exception of neglecting to explicitly encourage you to call
Chem.SanitizeMol() on your joined molecule before you do anything else with
it. In your case you'd call:
Chem.SanitizeMol(back)
This will lead to the error that Nik
I don't think I understand the question. The Conformer object is normally
attached to/associated with a mol object.

Hi Brian,
It's not that surprising. The RDKit is stricter about allowing unreasonable
chemistry that the tool the ChEMBL group uses to produce SMILES or mol
blocks.
There are always some molecules that the RDKit just won't process.
If you are concerned and see any in that group of failures that
Hi Pavel,
It is, unfortunately, not that easy.
The canonicalization algorithm does not use atomic aromaticity when
determining atom ordering, so as far as it is concerned there is no
difference between atoms 0 and 2 in either of your examples. What does get
used is the number of hydrogens, so you
Hi Jason,
There's no direct way to do this.
The easiest way that I can think of to approximate it would be to set the
ChiralTag on the possibly chiral atoms to CHI_TETRAHEDRAL_CW, call
assignStereoChemistry(), and then loop over the possibly chiral atoms again
to see if they have the absolute
Hi Francois,
The only partial charge implementations currently available in the RDKit
are the Gasteiger-Marsilli charges and the charges associated with MMFF.
Neither offers a way to decompose the charged into sigma/pi contributions.
Best,

Hi Katrina,
welcome to the RDKit community!

Hi Andreas,
That's a really good question, but I'm afraid that there's not good answer
for it: the new drawing code does not currently have an option to support
either black and white rendering or using custom colors for the elements.
I just created the github item for B rendering here:
Hi JP,
Python 2.6 is no longer supported (it's not supported by the python
community either). My recommendation for using the RDKit on Centos6 (really
on any system) would be to use anaconda python.

To further elaborate on this: the new 3D descriptors are currently
available in github and will be in the next release, but they aren't in the
2017.03 release.
