+DESCRIPTION
+    TopologicalPharmacophoreAtomTripletsFingerprints [ Ref 66, Ref 68-71 ]
+    class provides the following methods:
+
+    new, GenerateFingerprints, , GetDescription, GetAtomTripletIDs,
+    SetAtomTypesToUse, SetDistanceBinSize, SetMaxDistance, SetMinDistance,
+    StringifyTopologicalPharmacophoreAtomTripletsFingerprints
+
+    TopologicalPharmacophoreAtomTripletsFingerprints is derived from
+    Fingerprints class which in turn is derived from ObjectProperty base
+    class that provides methods not explicitly defined in
+    TopologicalPharmacophoreAtomTripletsFingerprints, Fingerprints or
+    ObjectProperty classes using Perl's AUTOLOAD functionality. These
+    methods are generated on-the-fly for a specified object property:
+
+        Set<PropertyName>(<PropertyValue>);
+        $PropertyValue = Get<PropertyName>();
+        Delete<PropertyName>();
+
+    Based on the values specified for AtomTypesToUse, pharmacophore atom
+    types are assigned to all non-hydrogen atoms in a molecule and a
+    distance matrix is generated. Using MinDistance, MaxDistance, and
+    DistanceBinSize values, a binned distance matrix is generated with lower
+    bound on the distance bin as the distance in distance matrix; the lower
+    bound on the distance bin is also used as the distance between atom
+    pairs for generation of atom triplet identifiers.
+
+    A pharmacophore atom triplets basis set is generated for all unique atom
+    triplets constituting atom pairs binned distances between --MinDistance
+    and --MaxDistance. The value of --UseTriangleInequality determines
+    whether the triangle inequality test is applied during generation of
+    atom triplets basis set. The lower distance bound, along with specified
+    pharmacophore types, is used during generation of atom triplet IDs.
+
+        Let:
+
+        P = Valid pharmacophore atom type
+
+        Px = Pharmacophore atom x
+        Py = Pharmacophore atom y
+        Pz = Pharmacophore atom z
+
+        Dmin = Minimum distance corresponding to number of bonds between two atoms
+        Dmax = Maximum distance corresponding to number of bonds between two atoms
+        D = Distance corresponding to number of bonds between two atom
+
+        Bsize  = Distance bin size
+        Nbins = Number of distance bins
+
+        Dxy = Distance or lower bound of binned distance between Px and Py
+        Dxz = Distance or lower bound of binned distance between Px and Pz
+        Dyz = Distance or lower bound of binned distance between Py and Pz
+
+        Then:
+
+        PxDyz-PyDxz-PzDxy = Pharmacophore atom triplet IDs for atom types Px,
+                            Py, and Pz
+
+        For example: H1-H1-H1, H2-HBA-H2 and so on.
+
+        For default values of Dmin = 1 , Dmax = 10 and Bsize = 2, the number of
+        distance bins, Nbins = 5, are:
+
+        [1, 2] [3, 4] [5, 6] [7, 8] [9 10]
+
+        and atom triplet basis set size is 2692.
+
+        Atom triplet basis set size for various values of Dmin, Dmax and Bsize in
+        conjunction with usage of triangle inequality is:
+
+        Dmin    Dmax   Bsize   UseTriangleInequality   TripletBasisSetSize
+        1       10     2       No                      4960
+        1       10     2       Yes                     2692 [ Default ]
+        2       12     2       No                      8436
+        2       12     2       Yes                     4494
+
+    Using binned distance matrix and pharmacohore atom types, occurrence of
+    unique pharmacohore atom triplets is counted.
+
+    The final pharmacophore atom triples count along with atom pair
+    identifiers involving all non-hydrogen atoms constitute pharmacophore
+    topological atom triplets fingerprints of the molecule.
+
+    For *ArbitrarySize* value of AtomTripletsSetSizeToUse, the fingerprint
+    vector correspond to only those topological pharmacophore atom triplets
+    which are present and have non-zero count. However, for *FixedSize*
+    value of AtomTripletsSetSizeToUse, the fingerprint vector contains all
+    possible valid topological pharmacophore atom triplets with both zero
+    and non-zero count values.
+
+    The current release of MayaChemTools generates the following types of
+    topological pharmacophore atom triplets fingerprints vector strings:

+            print "$TPATFP\n";
+
+    GetDescription
+            $Description = $TopologicalPharmacophoreAtomTripletsFP->GetDescription();
+
+        Returns a string containing description of topological pharmacophore
+        atom triplets fingerprints.
+
+    GenerateFingerprints
+            $TopologicalPharmacophoreAtomTripletsFP->GenerateFingerprints();
+
+        Generates topological pharmacophore atom triplets fingerprints and
+        returns *TopologicalPharmacophoreAtomTripletsFP*.
+
+    GetAtomTripletIDs
+            $AtomTripletsIDsRef = $TopologicalPharmacophoreATFP->GetAtomTripletIDs();
+            @AtomTripletIDs = $TopologicalPharmacophoreATFP->GetAtomTripletIDs();
+
+        Returns atom triplet IDs corresponding to atom pairs count values in
+        topological pharmacophore atom triplet fingerprints vector as an
+        array or reference to an array.
+
+    AtomTripletsSetSizeToUse
+            $TPAFP->AtomTripletsSetSizeToUse($Values);
+
+        Sets pharmacophore atom triplets set size to use for topological
+        pharmacophore fingerprints generation and returns
+        *TopologicalPharmacophoreAtomTripletsFingerprints*.
+
+        Possible values for pharmacophore atom triplets set size are:
+        *ArbitrarySize, FizedSize*. Default value: *ArbitrarySize*.
+
+        For *ArbitrarySize* value of AtomTripletsSetSizeToUse, the
+        fingerprint vector correspond to only those topological
+        pharmacophore atom triplets which are present and have non-zero
+        count. However, for *FixedSize* value of AtomTripletsSetSizeToUse,
+        the fingerprint vector contains all possible valid topological
+        pharmacophore atom triplets with both zero and non-zero count
+        values.
+
+    SetAtomTypesToUse
+            $TopologicalPharmacophoreAtomTripletsFP->SetAtomTypesToUse($ValuesRef);
+            $TopologicalPharmacophoreAtomTripletsFP->SetAtomTypesToUse(@Values);
+
+        Sets pharmacophore atom types to use for topological pharmacophore
+        fingerprints generation and returns
+        *TopologicalPharmacophoreAtomTripletsFingerprints*.
+
+        Possible values for pharmacophore atom types are: *Ar, CA, H, HBA,
+        HBD, Hal, NI, PI, RA*. Default value [ Ref 71 ] :
+        *HBD,HBA,PI,NI,H,Ar*.
+
+        The pharmacophore atom types abbreviations correspond to:
+
+            HBD: HydrogenBondDonor
+            HBA: HydrogenBondAcceptor
+            PI :  PositivelyIonizable
+            NI : NegativelyIonizable
+            Ar : Aromatic
+            Hal : Halogen
+            H : Hydrophobic
+            RA : RingAtom
+            CA : ChainAtom
+
+        *AtomTypes::FunctionalClassAtomTypes* module is used to assign
+        pharmacophore atom types. It uses following definitions [ Ref 60-61,
+        Ref 65-66 ]:
+
+            HydrogenBondDonor: NH, NH2, OH
+            HydrogenBondAcceptor: N[!H], O
+            PositivelyIonizable: +, NH2
+            NegativelyIonizable: -, C(=O)OH, S(=O)OH, P(=O)OH
+
+    SetDistanceBinSize
+            $TopologicalPharmacophoreAtomTripletsFP->SetDistanceBinSize($Value);
+
+        Sets distance bin size used to bin distances between atom pairs in
+        atom triplets and returns *TopologicalPharmacophoreAtomTriplesFP*.
+
+        For default MinDistance and MaxDistance values of 1 and 10 with
+        DistanceBinSize of 2 [ Ref 70 ], the following 5 distance bins are
+        generated:
+
+            [1, 2] [3, 4] [5, 6] [7, 8] [9 10]
+
+        The lower distance bound on the distance bin is uses to bin the
+        distance between atom pairs in atom triplets. So in the previous
+        example, atom pairs with distances 1 and 2 fall in first distance
+        bin, atom pairs with distances 3 and 4 fall in second distance bin
+        and so on.
+
+        In order to distribute distance bins of equal size, the last bin is
+        allowed to go past MaxDistance by up to distance bin size. For
+        example, MinDistance and MaxDistance values of 2 and 10 with
+        DistanceBinSize of 2 generates the following 6 distance bins:
+
+            [2, 3] [4, 5] [6, 7] [8, 9] [10 11]
+
+    SetMaxDistance
+            $TopologicalPharmacophoreAtomTriplesFP->SetMaxDistance($Value);
+
+        Sets maximum bond distance between atom pairs corresponding to atom
+        triplets for generating topological pharmacophore atom triplets
+        fingerprints and returns *TopologicalPharmacophoreAtomTriplesFP*.
+
+    SetMinDistance
+            $TopologicalPharmacophoreAtomTriplesFP->SetMinDistance($Value);
+
+        Sets minimum bond distance between atom pairs corresponding to atom
+        triplets for generating topological pharmacophore atom triplets
+        fingerprints and returns *TopologicalPharmacophoreAtomTriplesFP*.
+
+    StringifyTopologicalPharmacophoreAtomTripletsFingerprints
+            $String = $TopologicalPharmacophoreAtomTripletsFingerprints->
+                           StringifyTopologicalPharmacophoreAtomTripletsFingerprints();
+
+        Returns a string containing information about
+        *TopologicalPharmacophoreAtomTripletsFingerprints* object.
