Hello all,
I'm a newby in obabel and I need a bit of help.
I use obabel to convert a file from sdf to mol2 format because another
program requires such conversion.
The conversion is fine, and I get something like this (I only show the
ATOM block):
@ATOM
1 C 0.5825 -1.4943

Given a list of SMILES, we compute thermochemical parameters,
enthalpy, entropy etc. This list is generated by a code that cannot
distinguish cis/trans or chiral isomers but the
This question has come up before. Can I ask why you would find this useful?
As in, what are trying to do?

Another thing, once you detect the chiral atom all you have to do is modify
the SMILES. For example in "CCC(B)(O)C" the third carbon is chiral, now if
you put it like "CC[C@](B)(O)C" and "CC[C@@](B)(O)C" you can separate the
compounds. It's just a matter of editing the SMILES

For what I've read there isn't. But with pybel you can identify chiral
molecules and chiral atoms. Afetar that probably all you have to do is come
up with a way to alter the SMILES. Here's a page where someone describes
how to identify chiral atoms with pybel:
