Manually add bonds between atoms.
| molecule_in | MolecularDataType | Molecular data. |
| N. bonds to add | field | The number of bonds to be added to the molecule. The following pair of fields will be replicated this number of times. |
| Atom from | field | Index of the atom from which the added link starts. |
| Atom to | field | Index of the atom on which the added link ends. |
| molecule_out | MolecularDataType | Molecular data with bonds added. The bonds are marked as SPECIAL_BOND for rendering pourposes. |
