I have a ligand, I would like to score its current conformer using

Dear list,
I am a little bit worried.
If I start from the conformer given at the end of this message,
MMFF94 gives me a minimized conformer energy of -122.528
while UFF gives me 69.098 (I assume, both are in kcal/mol).
I am a little bit annoyed by the fact that the UFF energy

Maybe you can use this:

Hello,
Apparently, the homebrew recipe for rdkit is broken on Mac.
That's not very cool, since brew is the reference tool to install
software from source (automatically) on the Mac.

You should install the ones you are missing and test again.

There is mention of RPM distributions of RDKit

But on trying these:

Hello,
If the update of the binary packages for Ubuntu/Debian
is documented somewhere, it would help people who
want to make available binary packages of rdkit as soon as there
is a new rdkit release.
I think we should have a ppa for people who want to use
the bleeding edge version of rdkit.

Hello,
Is it possible to decompose partial charges with rdkit?
I am afraid that Gasteiger-Marsili (PEOE) is mostly about sigma bonds,
but I might be wrong.
