Re: [Open Babel] Split SDF file in chunks

I definitely agree. Perhaps a modification of the -m option, e.g. "-m 50" would be chunks of 50 molecules, and "-m 50p" would be 50 parts. In this way, "-m" on its own would be equivalent to "-m 1". The only problem would be if someone wrote "-m 2" by accident, instead of "-m 2p". - Noel On 4 Jun

Get the neighbouring atom (obatom_b) of obatom_a, and then use the information on the two atoms to get the associated OBBond with: my_obbond = my_obmol.GetBond(obatom_a, obatom_b). See the API for OBMol at http://openbabel.org/api/2.3/classOpenBabel_1_1OBMol.shtml. - Noel On 4 June 2011 09:34

[Open Babel] atom/bond association

2011-06-04 Thread Chris Mullins
Hi, I would like to be able to associate an atom with its bond type to a neighbouring atom using Pybel.  I've found out how to identify the neighbouring atoms (breadth-first) and can see how to get bond info too.  What I cannot see is a strategy for is matching the right neighbour atom with the
