DESCRIPTION

Generate topological pharmacophore atom pairs fingerprints [ Ref 60-62, Ref 65, Ref 68 ] for 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 .sdf and .sd. All other file names are ignored. All the SD files in a current directory can be specified either by *.sdf or the current directory name.

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. A pharmacophore atom pairs basis set is initialized for all unique possible pairs within --MinDistance and --MaxDistance range.

Let:
P = Valid pharmacophore atom type
Px = Pharmacophore atom type x
Py = Pharmacophore atom type y
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 atoms
Px-Dn-Py = Pharmacophore atom pair ID for atom types Px and Py at distance Dn
P = Number of pharmacophore atom types to consider
PPDn = Number of possible unique pharmacophore atom pairs at a distance Dn
PPT = Total number of possible pharmacophore atom pairs at all distances between Dmin and Dmax
Then:
PPD = (P * (P - 1))/2 + P
PPT = ((Dmax - Dmin) + 1) * ((P * (P - 1))/2 + P)
     = ((Dmax - Dmin) + 1) * PPD
So for default values of Dmin = 1, Dmax = 10 and P = 5,
PPD = (5 * (5 - 1))/2 + 5 = 15
PPT = ((10 - 1) + 1) * 15 = 150
The pharmacophore atom pairs bais set includes 150 values.
The atom pair IDs correspond to:
Px-Dn-Py = Pharmacophore atom pair ID for atom types Px and Py at distance Dn
For example: H-D1-H, H-D2-HBA, PI-D5-PI and so on

Using distance matrix and pharmacohore atom types, occurrence of unique pharmacohore atom pairs is counted. The contribution of each atom type to atom pair interaction is optionally weighted by specified --AtomTypesWeight before assigning its count to appropriate distance bin. Based on --NormalizationMethodology option, pharmacophore atom pairs count is optionally normalized. Additionally, pharmacohore atom pairs count is optionally fuzzified before or after the normalization controlled by values of --FuzzifyAtomPairsCount, --FuzzificationMode, --FuzzificationMethodology and --FuzzFactor options.

The final pharmacophore atom pairs count along with atom pair identifiers involving all non-hydrogen atoms, with optional normalization and fuzzification, constitute pharmacophore topological atom pairs fingerprints of the molecule.

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

OPTIONS

--AromaticityModel MDLAromaticityModel | TriposAromaticityModel | MMFFAromaticityModel | ChemAxonBasicAromaticityModel | ChemAxonGeneralAromaticityModel | DaylightAromaticityModel | MayaChemToolsAromaticityModel

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

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

--AtomPairsSetSizeToUse ArbitrarySize | FixedSize

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

Possible values: ArbitrarySize | FixedSize; Default value: ArbitrarySize.

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

-a, --AtomTypesToUse "AtomType1,AtomType2,..."

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

Possible values for pharmacophore atom types are: Ar, CA, H, HBA, HBD, Hal, NI, PI, RA. Default value [ Ref 60-62 ] : HBD,HBA,PI,NI,H.

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
--AtomTypesWeight "AtomType1,Weight1,AtomType2,Weight2..."

Weights of specified pharmacophore atom types to use during calculation of their contribution to atom pair count. Default value: None. Valid values: real numbers greater than 0. In general it's comma delimited list of valid atom type and its weight.

The weight values allow to increase the importance of specific pharmacophore atom type in the generated fingerprints. A weight value of 0 for an atom type eliminates its contribution to atom pair count where as weight value of 2 doubles its contribution.

--CompoundID DataFieldName or LabelPrefixString

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

For DataField value of --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, Cmpd, generates compound IDs which look like Cmpd<Number>.

Examples for DataField value of --CompoundIDMode:

MolID
ExtReg

Examples for LabelPrefix or MolNameOrLabelPrefix value of --CompoundIDMode:

Compound

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

--CompoundIDLabel text

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

--CompoundIDMode 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 FP | text | all values of --output option: use a SDFile(s) datafield value; use molname line from 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: DataField | MolName | LabelPrefix | MolNameOrLabelPrefix. Default value: LabelPrefix.

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

This is only used for CompoundID value of --DataFieldsMode option.

--DataFields "FieldLabel1,FieldLabel2,..."

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

This is only used for Specify value of --DataFieldsMode option.

Examples:

Extreg
MolID,CompoundName
-d, --DataFieldsMode All | Common | Specify | CompoundID

Specify how data fields in SDFile(s) are transferred to output CSV/TSV text file(s) along with generated fingerprints for text | all values of --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: All | Common | specify | CompoundID. Default value: CompoundID.

-f, --Filter Yes | No

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

--FingerprintsLabelMode FingerprintsLabelOnly | FingerprintsLabelWithIDs

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

Possible values: FingerprintsLabelOnly | FingerprintsLabelWithIDs. Default value: FingerprintsLabelOnly.

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

FingerprintsLabelWithIDs value of --FingerprintsLabelMode is ignored during ArbitrarySize value of --AtomPairsSetSizeToUse option and topological atom pairs IDs not appended to the label.

--FingerprintsLabel 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 --output. Default value: TopologicalPharmacophoreAtomPairsFingerprints.

--FuzzifyAtomPairsCount Yes | No

To fuzzify or not to fuzzify atom pairs count. Possible values: Yes or No. Default value: No.

--FuzzificationMode BeforeNormalization | AfterNormalization

When to fuzzify atom pairs count. Possible values: BeforeNormalization | AfterNormalizationYes. Default value: AfterNormalization.

--FuzzificationMethodology FuzzyBinning | FuzzyBinSmoothing

How to fuzzify atom pairs count. Possible values: FuzzyBinning | FuzzyBinSmoothing. Default value: FuzzyBinning.

In conjunction with values for options --FuzzifyAtomPairsCount, --FuzzificationMode and --FuzzFactor, --FuzzificationMethodology option is used to fuzzify pharmacophore atom pairs count.

Let:

Px = Pharmacophore atom type x
Py = Pharmacophore atom type y
PPxy = Pharmacophore atom pair between atom type Px and Py
PPxyDn = Pharmacophore atom pairs count between atom type Px and Py at distance Dn
PPxyDn-1 = Pharmacophore atom pairs count between atom type Px and Py at distance Dn - 1
PPxyDn+1 = Pharmacophore atom pairs count between atom type Px and Py at distance Dn + 1
FF = FuzzFactor for FuzzyBinning and FuzzyBinSmoothing

Then:

For FuzzyBinning:

PPxyDn = PPxyDn (Unchanged)
PPxyDn-1 = PPxyDn-1 + PPxyDn * FF
PPxyDn+1 = PPxyDn+1 + PPxyDn * FF

For FuzzyBinSmoothing:

PPxyDn = PPxyDn - PPxyDn * 2FF for Dmin < Dn < Dmax
PPxyDn = PPxyDn - PPxyDn * FF for Dn = Dmin or Dmax
PPxyDn-1 = PPxyDn-1 + PPxyDn * FF
PPxyDn+1 = PPxyDn+1 + PPxyDn * FF

In both fuzzification schemes, a value of 0 for FF implies no fuzzification of occurrence counts. A value of 1 during FuzzyBinning corresponds to maximum fuzzification of occurrence counts; however, a value of 1 during FuzzyBinSmoothing ends up completely distributing the value over the previous and next distance bins.

So for default value of --FuzzFactor (FF) 0.15, the occurrence count of pharmacohore atom pairs at distance Dn during FuzzyBinning is left unchanged and the counts at distances Dn -1 and Dn + 1 are incremented by PPxyDn * 0.15.

And during FuzzyBinSmoothing the occurrence counts at Distance Dn is scaled back using multiplicative factor of (1 - 2*0.15) and the occurrence counts at distances Dn -1 and Dn + 1 are incremented by PPxyDn * 0.15. In otherwords, occurrence bin count is smoothed out by distributing it over the previous and next distance value.

--FuzzFactor number

Specify by how much to fuzzify atom pairs count. Default value: 0.15. Valid values: For FuzzyBinning value of --FuzzificationMethodology option: between 0 and 1.0; For FuzzyBinSmoothing value of --FuzzificationMethodology option: between 0 and 0.5.

-h, --help

Print this help message.

-k, --KeepLargestComponent Yes | No

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

--MinDistance number

Minimum bond distance between atom pairs for generating topological pharmacophore atom pairs. Default value: 1. Valid values: positive integers including 0 and less than --MaxDistance.

--MaxDistance number

Maximum bond distance between atom pairs for generating topological pharmacophore atom pairs. Default value: 10. Valid values: positive integers and greater than --MinDistance.

-n, --NormalizationMethodology None | ByHeavyAtomsCount | ByAtomTypesCount

Normalization methodology to use for scaling the occurrence count of pharmacophore atom pairs within specified distance range. Possible values: None, ByHeavyAtomsCount or ByAtomTypesCount. Default value: None.

--OutDelim comma | tab | semicolon

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

--output SD | FP | text | all

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

-o, --overwrite

Overwrite existing files.

-q, --quote Yes | No

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

-r, --root RootName

New file name is generated using the root: <Root>.<Ext>. Default for new file names: <SDFileName><TopologicalPharmacophoreAtomPairsFP>.<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.

--ValuesPrecision number

Precision of atom pairs count real values which might be generated after normalization or fuzzification. Default value: up to 2 decimal places. Valid values: positive integers.

-v, --VectorStringFormat ValuesString, IDsAndValuesString | IDsAndValuesPairsString | ValuesAndIDsString | ValuesAndIDsPairsString

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

Default value during FixedSize value of --AtomPairsSetSizeToUse option: ValuesString. Default value during ArbitrarySize value of --AtomPairsSetSizeToUse option: IDsAndValuesString.

ValuesString option value is not allowed for ArbitrarySize value of --AtomPairsSetSizeToUse option.
