+=head1 DESCRIPTION
+
+Generate atom neighborhoods fingerprints  [ Ref 53-56, Ref 73 ] 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.
+
+The current release of MayaChemTools supports generation of atom neighborhoods fingerprints
+corresponding to following B<-a, --AtomIdentifierTypes>:
+
+    AtomicInvariantsAtomTypes, DREIDINGAtomTypes, EStateAtomTypes,
+    FunctionalClassAtomTypes, MMFF94AtomTypes, SLogPAtomTypes,
+    SYBYLAtomTypes, TPSAAtomTypes, UFFAtomTypes
+
+Based on the values specified for B<-a, --AtomIdentifierType> and B<--AtomicInvariantsToUse>,
+initial atom types are assigned to all non-hydrogen atoms in a molecule. Using atom neighborhoods
+around each non-hydrogen central atom corresponding to radii between specified values
+B<--MinNeighborhoodRadius> and B<--MaxNeighborhoodRadius>, unique atom types at
+each radii level are counted and an atom neighborhood identifier is generated.
+
+The format of an atom neighborhood identifier around a central non-hydrogen atom at a
+specific radius is:
+
+    NR<n>-<AtomType>-ATC<n>
+
+    NR: Neighborhood radius
+    AtomType: Assigned atom type
+    ATC: Atom type count
+
+The atom neighborhood identifier for a non-hydrogen central atom corresponding to all specified radii
+is generated by concatenating neighborhood identifiers at each radii by colon as a delimiter:
+
+    NR<n>-<AtomType>-ATC<n>:NR<n>-<AtomType>-ATC<n>:...
+
+The atom neighborhood identifiers for all non-hydrogen central atoms at all specified radii are
+concatenated using space as a delimiter and constitute atom neighborhood fingerprint of the molecule.

+
+This value is used during I<FunctionalClassAtomTypes> value of B<a, --AtomIdentifierType>
+option. It's a list of comma separated valid functional classes.
+
+Possible values for atom functional classes are: I<Ar, CA, H, HBA, HBD, Hal, NI, PI, RA>.
+Default value [ Ref 24 ]: I<HBD,HBA,PI,NI,Ar,Hal>.
+
+The functional class abbreviations correspond to:
+
+    HBD: HydrogenBondDonor
+    HBA: HydrogenBondAcceptor
+    PI :  PositivelyIonizable
+    NI : NegativelyIonizable
+    Ar : Aromatic
+    Hal : Halogen
+    H : Hydrophobic
+    RA : RingAtom
+    CA : ChainAtom
+
+ Functional class atom type specification for an atom corresponds to:
+
+    Ar.CA.H.HBA.HBD.Hal.NI.PI.RA
+
+I<AtomTypes::FunctionalClassAtomTypes> module is used to assign functional class atom
+types. It uses following definitions [ Ref 60-61, Ref 65-66 ]:
+
+    HydrogenBondDonor: NH, NH2, 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 FP or CSV/TSV text file(s) used during I<CompoundID> value
+of B<--DataFieldsMode> option. Default: 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: 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.

+
+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<-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<--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<AtomNeighborhoodsFingerprints>.

+
+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<--MinNeighborhoodRadius> I<number>
+
+Minimum atom neighborhood radius for generating atom neighborhoods. Default value: I<0>.
+Valid values: positive integers and less than B<--MaxNeighborhoodRadius>. Neighborhood
+radius of zero corresponds to list of non-hydrogen atoms.

+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<-r, --root> I<RootName>
+
+New file name is generated using the root: <Root>.<Ext>. Default for new file names:
+<SDFileName><AtomNeighborhoodsFP>.<Ext>. The file type determines <Ext>
+value. The sdf, fpf, csv, and tsv <Ext> values are used for SD, comma/semicolon, and tab
+delimited text files, respectively.This option is ignored for multiple input files.
+
+=item B<-w, --WorkingDir> I<DirName>
