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:
mol_weight [Molecular Weight]
exact_mass [Isotopic Mass]
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
babel(1), obchiral(1), obfit(1), obgrep(1), obrotate(1).

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