obprop -- print standard molecular properties


obprop filename


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.
