[OpenBabel-Devel] How to get force fields parameters

[iwao a. <iwa...@gm...>]

Hello,
I am wondering if there is a way to get force fields parameters through OB
function.

When I ran some codes like:

   OBMol mol;
   OBForceField* pFF=FindForceField("GAFF");

   pFF->SetLogFile(&cout);
   pFF->(OBFF_LOGLVL_HIGH);
   pFF->Setup(mol);
   pFF->E_Bond();

then the following log was displayed:

   ATOM TYPES   BOND    IDEAL    FORCE
    I    J     LENGTH  LENGTH  CONSTANT    DELTA   ENERGY
  --------------------------------------------------------
   o   c   1.221   1.214   2713.046      0.007  0.122
  ca   ca  1.406   1.387   2002.965      0.009   0.150
                     :

Can I get values like these ( atom types, ideal lengths and force constants
) through any OB class function?
(I have a plan to write a charmm-style psf/parameter file generator.)

Thank you in advance.
