I need to determine the number of hydrophobic carbons in a compound. when I
loop through the atoms with OBAtom, I can count carbons by incrementing when
atom.IsCarbon = true. However, what atom.property should I use to determine if
the carbon is polar? Is it heterovalence?
One of the weights for a particular LogS method requires the number of
hydrophobic carbons. So I added hydrogens, transformed to three dimensions,
energy minimized with gradient descent (don't need conformers here), then
parsed the mol2 output to fetch the partial charge on the far right
See:

Look at the first section, "4.1 SMARTS Atomic Primitives" section. Both
"x" and "X" are valid, but not with spaces.

Hi,
I would like to remove duplicate conformers judged by RMSD from MD frames to
generated many unique conformers for a system. Is obabel capable of doing that?

I am using OB and SmartsPattern fetching in 2D compounds, and need to fetch a
published SMARTS which looks like the following:
[CX4;H]([#6 × 4,c,F,Cl,Br,I])([#6 × 4,c,F,Cl,Br,I])[#6 × 4,c,F,Cl,Br,I]
and there are actually spaces around the × symbols between the 6 and 4.
Question is, should I
It's probably a capital X4 without spaces messed up by the journal. What's
the ref?
