Hi Shaozhen,
that parameter can be accessed from Python, it is called maxProducts,
and it defaults to 1000 as described in the Python API docs:
http://www.rdkit.org/docs/source/rdkit.Chem.rdChemReactions.html?highlight=runreactants#rdkit.Chem.rdChemReactions.ChemicalReaction.RunReactants
Cheers,
p.

I don't know how you access that parameter from Pythonn, I'm afraid.
Maybe someone else here can help?

Dear Atkinson:
From rdkit document, I found there is a parameter named numProducts
in RunReactants function, this parameter can limit the products
number, and it defaults to 1000.
How can I change this parameter??If I change this number to a small
one , I may change the run time.
I hope to solve this problem very much.
Thanks a lot.
Kind regards
Shaozhen

Shaozhen,
?0?2?0?2?0?2 OK, this doesn't work for me either on my Mac, but does work as
expected on Linux (RHEL7). I'm afraid I really don't know why!
?0?2?0?2?0?2 I also don't know if this is something is to do with the version
of MacOS; I tend to do development on a Mac, but run large jobs on
Linux, so I might simply not have noticed this failure on the Mac before.

Hi?0?2Atkinson:
Thanks so much, and I have taken your?0?2 advice.(I saved the code as
timeout.py ,and put it on '/Users/ding/Desktop' )
But?0?2 it cannot resolve my problems.
My operating system is Mac OS.
It works well in the function mytest (in the following code).
But It cannot work in the function reaction_predict_outside (in the
following code).
If I don??t stop this function, it always make my computer down.
Could you please help me to solve this trouble?
Kind regards.

Shaozen,
?0?2?0?2?0?2 I have successfully used the solution outlined in this SO answer
...
https://stackoverflow.com/questions/2281850/timeout-function-if-it-takes-too-long-to-finish
?0?2?0?2?0?2 It uses Posix signals so it wouldn't work on older versions of
Windows (I don't know about Windows 10, what with this new
Linux-compatibility layer). It also doesn't work when running under
mod_wsgi.

if this functions cannnot return result within 3s, I will make it
return a empty set.
Could you help me deal with this problems?
