Hi,
your molecule itself is not ok - the Sn has a larger valence then
permitted. There was a similar case recently about phosphor. I would guess
that you should fix your molecule first.
In your code example below your molecule m is None and hence the rest will
not work.
Hope that helps
Cheers
Nik

[Rdkit-discuss] How to trap the exceptions in RDKit?
Hi,
I have the following code which raises an exception because the molecule
is not up to its expectations. But I can?t find a way to trap the
exception. Can someone suggest one, please?
from rdkit import Chem
from rdkit.Chem import AvailDescriptors
from rdkit.Chem import Crippen
m=Chem.MolFromSmiles('c1ccc2c(c1)/C=N/c3ccccc3S[Ti]O2.[CH]1[CH][CH][CH][CH]1.Cl[Sn-](Cl)(Cl)(Cl)Cl')
# I tried this way
molog = Crippen.MolLogP(m)
print molog
# and also this way first
if AvailDescriptors.descDict['MolLogP'](m):
mollogp = AvailDescriptors.descDict['MolLogP'](m)
I also wanted to calc. NumHDonors and NumHAcceptors. But if it failed on
one descriptor, will it fail on other descriptors as well?
Any suggestions?
Thanks
Sridhar
p.s. to Eddie. Turned out my server has the 11g client and the
installation on the server works fine. I guess I must have missed a line
or two of instructions that the client must be 11g?s and not the DB
itself. My PC had oracle 9 and 10 clients.

Hi,
Being not an Oracle user, I cannot give you a concrete answer, but a quick
Google search indicates that it might be a version inconsistency between
the client and the server. Are you sure you are connecting to 11g? Please
contact your database administrator for problems regarding Oracle database
or ask the folks on the cx_Oracle mailing list:

Hi,
I have downloaded the ?Windows x86 Installer (Oracle 11g, Python 2.5)? to

I have originally used the connstr=user/p...@chemdev' and this gave me the
same error as above.
Then I found the above syntax in the cx_oracle_doc folder?s readme.txt and
am lost now.
MY PC has Windows XP, Oracle is on a different server (with a TNS entry
?chemdev?) and I just added TNS_ADMIN Registry_entry and the path of
TNS_ADMIN to the PATH env. Variable.

Any thoughts?
Many thanks

Hi Sridhar,
congrats on getting things working. One more comment - maybe you want to
post these kind of questions rather in the discuss than the devel list. It
is much more populated and you will for sure get replies quicker.
Cheers

Re: [Rdkit-devel] How to build the RDKit?
Hi Sridhar,
Congratulations! If from rdkit import Chem gives you >>>, then it is very
good sign that things are all in place.
To load molecules from Oracle database, you need a database connector
called cx_Oracle. After installing this module, you will be able to send
SQL statement to Oracle to retrieve molecule SMILES or SDF, depending on
how molecules are stored in your database. You might need to consult your
database administrator.
To download cx_Oracle: http://cx-oracle.sourceforge.net/
For a simple example about how to use it:
http://wiki.oracle.com/page/Python
Check Section 14 of the Getting Started in Python Guide for a complete
list of descriptors you can calculate using RDKit:
http://rdkit.org/GettingStartedInPython.pdf
Regards,
Eddie

Hi Nik,
Looks like I had a version issue with the RDkit I downloaded. I needed
Q22010_1 for Python2.5 but I downloaded Q22009_1 in which, it was looking
for Python2.5 (hardcoded path from one of the libs, looked like) when I
ran the test command (hence I downloaded and installed Python2.5 and
removed 2.6).
Now that I have a clean install of Py2.5 and fresh download of RDkit
Q22010_1 for Py2.5, the test command ran well and passed the test.
I just have to go to the next step.
I need to create molLogP, NumHAcceptors, NumHDonors etc.. values for a
given molecule.
My molecules are actually stored in an Oracle DB.
So, Where do I begin?
I just got your other mail. The install is set and OK now as it seems.
I ran the command ?from rdkit import Chem? from the command-line and it
put me back to the >>> prompt, no add?l msgs.
As for sending to the whole group, it was an honest mistake. I just
clicked ?Reply?. Some other lists that I subscribed to, send to the list
automagically. I realized my mistake when I didn?t receive the mail back
to me and fixed it in this one.
Regards,
Sridhar
