Detailed Description

Molecule Class.

The most important class in Open Babel is OBMol, or the molecule class. The OBMol class is designed to store all the basic information associated with a molecule, to make manipulations on the connection table of a molecule facile, and to provide member functions which automatically perceive information about a molecule. A guided tour of the OBMol class is a good place to start.

An OBMol class can be declared:

      OBMol mol;

For example:

      #include <iostream.h>

      #include <openbabel/mol.h>
      #include <openbabel/obconversion.h>
      int main(int argc,char **argv)
      {
      OBConversion conv(&cin,&cout);
      if(conv.SetInAndOutFormats("SDF","MOL2"))
      { 
      OBMol mol;
      if(conv.Read(&mol))
      ...manipulate molecule 
    
      conv->Write(&mol);
      }
      return(1);
      }

will read in a molecule in SD file format from stdin (or the C++ equivalent cin) and write a MOL2 format file out to standard out. Additionally, The input and output formats can be altered using the OBConversion class

Once a molecule has been read into an OBMol (or created via other methods) the atoms and bonds can be accessed by the following methods:

      OBAtom *atom;
      atom = mol.GetAtom(5); //random access of an atom

or

      OBBond *bond;
      bond = mol.GetBond(14); //random access of a bond

or

      FOR_ATOMS_OF_MOL(atom, mol) // iterator access (see OBMolAtomIter)

or

      FOR_BONDS_OF_MOL(bond, mol) // iterator access (see OBMolBondIter)

It is important to note that atom arrays currently begin at 1 and bond arrays begin at 0. Requesting atom 0 (

      OBAtom *atom = mol.GetAtom(0);

will result in an error, but

      OBBond *bond = mol.GetBond(0);

is perfectly valid. Note that this is expected to change in the near future to simplify coding and improve efficiency.

The ambiguity of numbering issues and off-by-one errors led to the use of iterators in Open Babel. An iterator is essentially just a pointer, but when used in conjunction with Standard Template Library (STL) vectors it provides an unambiguous way to loop over arrays. OBMols store their atom and bond information in STL vectors. Since vectors are template based, a vector of any user defined type can be declared. OBMols declare vector<OBAtom*> and vector<OBBond*> to store atom and bond information. Iterators are then a natural way to loop over the vectors of atoms and bonds.

A variety of predefined iterators have been created to simplify common looping requests (e.g., looping over all atoms in a molecule, bonds to a given atom, etc.)

      #include <openbabel/obiter.h>
      ...
      #define FOR_ATOMS_OF_MOL(a,m)     for( OBMolAtomIter     a(m); a; ++a )
      #define FOR_BONDS_OF_MOL(b,m)     for( OBMolBondIter     b(m); b; ++b )
      #define FOR_NBORS_OF_ATOM(a,p)    for( OBAtomAtomIter    a(p); a; ++a )
      #define FOR_BONDS_OF_ATOM(b,p)    for( OBAtomBondIter    b(p); b; ++b )
      #define FOR_RESIDUES_OF_MOL(r,m)  for( OBResidueIter     r(m); r; ++r )
      #define FOR_ATOMS_OF_RESIDUE(a,r) for( OBResidueAtomIter a(r); a; ++a )
      ...

These convenience functions can be used like so:

      #include <openbabel/obiter.h>
      #include <openbabel/mol.h>

      OBMol mol;
      double exactMass = 0.0;
      FOR_ATOMS_OF_MOL(a, mol)
      {
      exactMass +=  a->GetExactMass();
      }

Note that with these convenience macros, the iterator "a" (or whichever name you pick) is declared for you -- you do not need to do it beforehand.

bool AssignSpinMultiplicity ( bool NoImplicitH = false )

set spin multiplicity for H-deficient atoms

If NoImplicitH is true then the molecule has no implicit hydrogens. Individual atoms on which ForceNoH() has been called also have no implicit hydrogens. If NoImplicitH is false (the default), then if there are any explicit hydrogens on an atom then they constitute all the hydrogen on that atom. However, a hydrogen atom with its _isotope!=0 is not considered explicit hydrogen for this purpose. In addition, an atom which has had ForceImplH()called for it is never considered hydrogen deficient, e.g. unbracketed atoms in SMILES. Any discrepancy with the expected atom valency is interpreted as the atom being a radical of some sort and iits _spinMultiplicity is set to 2 when it is one hydrogen short and 3 when it is two hydrogens short and similarly for greater hydrogen deficiency.

So SMILES C[CH] is interpreted as methyl carbene, CC[H][H] as ethane, and CC[2H] as CH3CH2D.
