- Parameters
 - 
  
    | n_non_star_atoms | Number of non-star atoms.  | 
    | n_star_atoms | Number of star atoms.  | 
    | atom_index_orig | Original atom indices as supplied.  | 
    | atom_index_fin | Final atom indices, with -1 for star atoms.  | 
    | n_sgroups | Number of S-groups.  | 
    | n_3d_constraints | Number of 3D constraints.  | 
    | n_collections | Number of collections.  | 
    | n_non_haptic_bonds | Number of non-haptic bonds.  | 
    | n_haptic_bonds | Number of haptic bonds.  | 
    | haptic_bonds | Pointer to the list of haptic bonds (int* contains bond type, non-star atom number, nendpts, then endpts themselves).  | 
    | n_steabs | Number of absolute stereo groups.  | 
    | steabs | Pointer to the list of absolute stereo groups (e.g. R and S).  | 
    | n_sterel | Number of relative stereo groups.  | 
    | sterel | Pointer to the list of relative stereo groups (OR - describes the orientation of groups relative to each other, such as in cis- and trans-isomers).  | 
    | n_sterac | Number of racemic stereo groups.  | 
    | sterac | Pointer to the list of racemic stereo groups (AND - equal 50:50 mixture of two enantiomers of a chiral molecule).  |
