obprop(1) print standard molecular properties




The obprop program is a tool to print a set of standard molecular properties for all molecules in a file. It also serves as example code for using the Open Babel library (libopenbabel).

Output format includes:
name [Name ]
formula [Formula ]
mol_weight [Molecular Weight ]
exact_mass [Isotopic Mass ]
canonical_SMILES [String ]
num_atoms [Number ]
num_bonds [Number ]
num_residues [Number ]
sequence [Residue Sequence ]
num_rings [Number of Rings (by SSSR) ]
logP [Number (octanol-water partition) ]
PSA [Number (topological polar surface area) ]
MR [Number (molar refractivity) ]

The "$$$" is the separator between multiple molecular entries in a file

The obprop program was contributed by An Fabien Fontaine

An -nosplit Open Babel is developed by a cast of many, including currrent maintainers An Geoff Hutchison , An Chris Morley , An Michael Banck , and innumerable others who have contributed fixes and additions. For more contributors to Open Babel, see <http://openbabel.org/wiki/THANKS>
