=head1 DESCRIPTION

Generate topological pharmacophore atom triplets fingerprints [ Ref 66, Ref 68-71 ] for
I<SDFile(s)> and create appropriate SD, FP or CSV/TSV text file(s) containing fingerprints vector
strings corresponding to molecular fingerprints.

Multiple SDFile names are separated by spaces. The valid file extensions are I<.sdf>
and I<.sd>. All other file names are ignored. All the SD files in a current directory
can be specified either by I<*.sdf> or the current directory name.

Based on the values specified for B<--AtomTypesToUse>, pharmacophore atom types are
assigned to all non-hydrogen atoms in a molecule and a distance matrix is generated.
Using B<--MinDistance>, B<--MaxDistance>, and B<--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 B<--MinDistance> and B<--MaxDistance>. The value
of B<--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 I<ArbitrarySize> value of B<--AtomTripletsSetSizeToUse> option, the fingerprint vector correspond to
only those topological pharmacophore atom triplets which are present and have non-zero count. However,
for I<FixedSize> value of B<--AtomTripletsSetSizeToUse> option, the fingerprint vector contains all possible
valid topological pharmacophore atom triplets with both zero and non-zero count values.

=over 4

=item B<--AromaticityModel> I<MDLAromaticityModel | TriposAromaticityModel | MMFFAromaticityModel | ChemAxonBasicAromaticityModel | ChemAxonGeneralAromaticityModel | DaylightAromaticityModel | MayaChemToolsAromaticityModel>

Specify aromaticity model to use during detection of aromaticity. Possible values in the current
release are: I<MDLAromaticityModel, TriposAromaticityModel, MMFFAromaticityModel,
ChemAxonBasicAromaticityModel, ChemAxonGeneralAromaticityModel, DaylightAromaticityModel
or MayaChemToolsAromaticityModel>. Default value: I<MayaChemToolsAromaticityModel>.

The supported aromaticity model names along with model specific control parameters
are defined in B<AromaticityModelsData.csv>, which is distributed with the current release
and is available under B<lib/data> directory. B<Molecule.pm> module retrieves data from
this file during class instantiation and makes it available to method B<DetectAromaticity>
for detecting aromaticity corresponding to a specific model.

=item B<--AtomTripletsSetSizeToUse> I<ArbitrarySize | FixedSize>

Atom triplets set size to use during generation of topological pharmacophore atom triplets
fingerprints.

Possible values: I<ArbitrarySize | FixedSize>; Default value: I<ArbitrarySize>.

For I<ArbitrarySize> value of B<--AtomTripletsSetSizeToUse> option, the fingerprint vector
correspond to only those topological pharmacophore atom triplets which are present and
have non-zero count. However, for I<FixedSize> value of B<--AtomTripletsSetSizeToUse>
option, the fingerprint vector contains all possible valid topological pharmacophore atom
triplets with both zero and non-zero count values.

=item B<-a, --AtomTypesToUse> I<"AtomType1,AtomType2,...">

Pharmacophore atom types to use during generation of topological phramacophore
atom triplets. It's a list of comma separated valid pharmacophore atom types.

Possible values for pharmacophore atom types are: I<Ar, CA, H, HBA, HBD, Hal, NI, PI, RA>.
Default value [ Ref 71 ] : I<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

I<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

=item B<--CompoundID> I<DataFieldName or LabelPrefixString>

This value is B<--CompoundIDMode> specific and indicates how compound ID is generated.

For I<DataField> value of B<--CompoundIDMode> option, it corresponds to datafield label name
whose value is used as compound ID; otherwise, it's a prefix string used for generating compound
IDs like LabelPrefixString<Number>. Default value, I<Cmpd>, generates compound IDs which
look like Cmpd<Number>.

Examples for I<DataField> value of B<--CompoundIDMode>:

    MolID
    ExtReg

Examples for I<LabelPrefix> or I<MolNameOrLabelPrefix> value of B<--CompoundIDMode>:

    Compound

The value specified above generates compound IDs which correspond to Compound<Number>
instead of default value of Cmpd<Number>.

=item B<--CompoundIDLabel> I<text>

Specify compound ID column label for CSV/TSV text file(s) used during I<CompoundID> value
of B<--DataFieldsMode> option. Default value: I<CompoundID>.

=item B<--CompoundIDMode> I<DataField | MolName | LabelPrefix | MolNameOrLabelPrefix>

Specify how to generate compound IDs and write to FP or CSV/TSV text file(s) along with generated
fingerprints for I<FP | text | all> values of B<--output> option: use a I<SDFile(s)> datafield value;
use molname line from I<SDFile(s)>; generate a sequential ID with specific prefix; use combination
of both MolName and LabelPrefix with usage of LabelPrefix values for empty molname lines.

Possible values: I<DataField | MolName | LabelPrefix | MolNameOrLabelPrefix>.
Default value: I<LabelPrefix>.

For I<MolNameAndLabelPrefix> value of B<--CompoundIDMode>, molname line in I<SDFile(s)> takes
precedence over sequential compound IDs generated using I<LabelPrefix> and only empty molname
values are replaced with sequential compound IDs.

This is only used for I<CompoundID> value of B<--DataFieldsMode> option.

=item B<--DataFields> I<"FieldLabel1,FieldLabel2,...">

Comma delimited list of I<SDFiles(s)> data fields to extract and write to CSV/TSV text file(s) along
with generated fingerprints for I<text | all> values of B<--output> option.

This is only used for I<Specify> value of B<--DataFieldsMode> option.

Examples:

    Extreg
    MolID,CompoundName

=item B<-d, --DataFieldsMode> I<All | Common | Specify | CompoundID>

Specify how data fields in I<SDFile(s)> are transferred to output CSV/TSV text file(s) along
with generated fingerprints for I<text | all> values of B<--output> option: transfer all SD
data field; transfer SD data files common to all compounds; extract specified data fields;
generate a compound ID using molname line, a compound prefix, or a combination of both.
Possible values: I<All | Common | specify | CompoundID>. Default value: I<CompoundID>.

=item B<--DistanceBinSize> I<number>

Distance bin size used to bin distances between atom pairs in atom triplets. Default value: I<2>.
Valid values: positive integers.

For default B<--MinDistance> and B<--MaxDistance> values of 1 and 10 with  B<--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 B<--MaxDistance>
by up to distance bin size. For example, B<--MinDistance> and B<--MaxDistance> values of 2 and 10
with B<--DistanceBinSize> of 2 generates the following 6 distance bins:

    [2, 3] [4, 5] [6, 7] [8, 9] [10 11]

=item B<-f, --Filter> I<Yes | No>

Specify whether to check and filter compound data in SDFile(s). Possible values: I<Yes or No>.
Default value: I<Yes>.

By default, compound data is checked before calculating fingerprints and compounds containing
atom data corresponding to non-element symbols or no atom data are ignored.

=item B<--FingerprintsLabelMode> I<FingerprintsLabelOnly | FingerprintsLabelWithIDs>

Specify how fingerprints label is generated in conjunction with B<--FingerprintsLabel> option value:
use fingerprints label generated only by B<--FingerprintsLabel> option value or append topological
atom pair count value IDs to B<--FingerprintsLabel> option value.

Possible values: I<FingerprintsLabelOnly | FingerprintsLabelWithIDs>. Default value:
I<FingerprintsLabelOnly>.

Topological atom pairs IDs appended to B<--FingerprintsLabel> value during I<FingerprintsLabelWithIDs>
values of B<--FingerprintsLabelMode>  correspond to atom pair count values in fingerprint vector string.

I<FingerprintsLabelWithIDs> value of B<--FingerprintsLabelMode> is ignored during I<ArbitrarySize> value
of B<--AtomTripletsSetSizeToUse> option and topological atom triplets IDs not appended to the label.

=item B<--FingerprintsLabel> I<text>

SD data label or text file column label to use for fingerprints string in output SD or
CSV/TSV text file(s) specified by B<--output>. Default value: I<TopologicalPharmacophoreAtomTripletsFingerprints>.

=item B<-h, --help>

Print this help message.

=item B<-k, --KeepLargestComponent> I<Yes | No>

Generate fingerprints for only the largest component in molecule. Possible values:
I<Yes or No>. Default value: I<Yes>.

For molecules containing multiple connected components, fingerprints can be generated
in two different ways: use all connected components or just the largest connected
component. By default, all atoms except for the largest connected component are
deleted before generation of fingerprints.

=item B<--MinDistance> I<number>

Minimum bond distance between atom pairs corresponding to atom triplets for generating
topological pharmacophore atom triplets. Default value: I<1>. Valid values: positive integers and
less than B<--MaxDistance>.

=item B<--MaxDistance> I<number>

Maximum bond distance between atom pairs corresponding to atom triplets for generating
topological pharmacophore atom triplets. Default value: I<10>. Valid values: positive integers and
greater than B<--MinDistance>.

=item B<--OutDelim> I<comma | tab | semicolon>

Delimiter for output CSV/TSV text file(s). Possible values: I<comma, tab, or semicolon>
Default value: I<comma>.

=item B<--output> I<SD | FP | text | all>

Type of output files to generate. Possible values: I<SD, FP, text, or all>. Default value: I<text>.

=item B<-o, --overwrite>

Overwrite existing files.

=item B<-q, --quote> I<Yes | No>

Put quote around column values in output CSV/TSV text file(s). Possible values:
I<Yes or No>. Default value: I<Yes>.

=item B<-r, --root> I<RootName>

New file name is generated using the root: <Root>.<Ext>. Default for new file names:
<SDFileName><TopologicalPharmacophoreAtomTripletsFP>.<Ext>. The file type determines <Ext> value.
The sdf, fpf, csv, and tsv <Ext> values are used for SD, FP, comma/semicolon, and tab
delimited text files, respectively.This option is ignored for multiple input files.

=item B<-u, --UseTriangleInequality> I<Yes | No>

Specify whether to imply triangle distance inequality test to distances between atom pairs in
atom triplets during generation of atom triplets basis set generation. Possible values:
I<Yes or No>. Default value: I<Yes>.

Triangle distance inequality test implies that distance or binned distance between any two atom
pairs in an atom triplet must be less than the sum of distances or binned distances between other
two atoms pairs and greater than the difference of their distances.

    For atom triplet PxDyz-PyDxz-PzDxy to satisfy triangle inequality:

    Dyz > |Dxz - Dxy| and Dyz < Dxz + Dxy
    Dxz > |Dyz - Dxy| and Dyz < Dyz + Dxy
    Dxy > |Dyz - Dxz| and Dxy < Dyz + Dxz

=item B<-v, --VectorStringFormat> I<ValuesString, IDsAndValuesString | IDsAndValuesPairsString | ValuesAndIDsString | ValuesAndIDsPairsString>

Format of fingerprints vector string data in output SD, FP or CSV/TSV text file(s) specified by
B<--output> option. Possible values: I<ValuesString, IDsAndValuesString | IDsAndValuesPairsString |
ValuesAndIDsString | ValuesAndIDsPairsString>. Defaultvalue: I<ValuesString>.

Default value during I<FixedSize> value of B<--AtomTripletsSetSizeToUse> option: I<ValuesString>. Default
value during I<ArbitrarySize> value of B<--AtomTripletsSetSizeToUse> option: I<IDsAndValuesString>.

I<ValuesString> option value is not allowed for I<ArbitrarySize> value of B<--AtomTripletsSetSizeToUse>
option.
