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 extended connectivity fingerprints +corresponding to following B<-a, --AtomIdentifierTypes>: + + AtomicInvariantsAtomTypes, DREIDINGAtomTypes, EStateAtomTypes, + FunctionalClassAtomTypes, MMFF94AtomTypes, SLogPAtomTypes, + SYBYLAtomTypes, TPSAAtomTypes, UFFAtomTypes + +Based on values specified for B<-a, --AtomIdentifierType>, B<--AtomicInvariantsToUse> +and B<--FunctionalClassesToUse>, initial atom types are assigned to all non-hydrogen atoms in +a molecule and these atom types strings are converted into initial atom identifier integers using +B<TextUtil::HashCode> function. The duplicate atom identifiers are removed. + +For B<-n, --NeighborhoodRadius> value of I<0>, the initial set of unique atom identifiers comprises +the molecule fingerprints. Otherwise, atom neighborhoods are generated for each non-hydrogen +atom up to specified B<-n, --NeighborhoodRadius> value. For each non-hydrogen central atom +at a specific radius, its neighbors at next radius level along with their bond orders and previously +calculated atom identifiers are collected which in turn are used to generate a new integer +atom identifier; the bond orders and atom identifier pairs list is first sorted by bond order +followed by atom identifiers to make these values graph invariant. + +After integer atom identifiers have been generated for all non-hydrogen atoms at all specified +neighborhood radii, the duplicate integer atom identifiers corresponding to same hash code +value generated using B<TextUtil::HashCode> are tracked by keeping the atom identifiers at +lower radius. Additionally, all structurally duplicate integer atom identifiers at each specified +radius are also tracked by identifying equivalent atoms and bonds corresponding to substructures +used for generating atom identifier and keeping integer atom identifier with lowest value. + +For I<ExtendedConnnectivity> value of fingerprints B<-m, --mode>, the duplicate identifiers are +removed from the list and the unique atom identifiers constitute the extended connectivity +fingerprints of a molecule. + +For I<ExtendedConnnectivityCount> value of fingerprints B<-m, --mode>, the occurrence of each +unique atom identifiers appears is counted and the unique atom identifiers along with their +count constitute the extended connectivity fingerprints of a molecule. + +For I<ExtendedConnectivityBits> value of fingerprints B<-m, --mode>, the unique atom identifiers +are used as a random number seed to generate a random integer value between 0 and B<--Size> which +in turn is used to set corresponding bits in the fingerprint bit-vector string. + +Example of I<SD> file containing extended connectivity fingerprints string data: + + ... ... + ... ... + $$$$ + ... ... + ... ... + ... ... + 41 44 0 0 0 0 0 0 0 0999 V2000 + -3.3652 1.4499 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 + ... ... + 2 3 1 0 0 0 0 + ... ... + M END + > <CmpdID> + Cmpd1 + + > <ExtendedConnectivityFingerprints> + FingerprintsVector;ExtendedConnectivity:AtomicInvariantsAtomTypes:Radiu + s2;60;AlphaNumericalValues;ValuesString;73555770 333564680 352413391 66 + 6191900 1001270906 1371674323 1481469939 1977749791 2006158649 21414087 + 99 49532520 64643108 79385615 96062769 273726379 564565671 855141035 90 + 6706094 988546669 1018231313 1032696425 1197507444 1331250018 133853... + + $$$$ + ... ... + ... ... + +Example of I<FP> file containing extended connectivity fingerprints string data: + + # + # Package = MayaChemTools 7.4 + # Release Date = Oct 21, 2010 + # + # TimeStamp = Fri Mar 11 14:43:57 2011 + # + # FingerprintsStringType = FingerprintsVector + # + # Description = ExtendedConnectivity:AtomicInvariantsAtomTypes:Radius2 + # VectorStringFormat = ValuesString + # VectorValuesType = AlphaNumericalValues + # + Cmpd1 60;73555770 333564680 352413391 666191900 1001270906 137167432... + Cmpd2 41;73555770 333564680 666191900 1142173602 1363635752 14814699... + ... ... + ... .. + +Example of CSV I<Text> file containing extended connectivity fingerprints string data: + + "CompoundID","ExtendedConnectivityFingerprints" + "Cmpd1","FingerprintsVector;ExtendedConnectivity:AtomicInvariantsAtomTy + pes:Radius2;60;AlphaNumericalValues;ValuesString;73555770 333564680 352 + 413391 666191900 1001270906 1371674323 1481469939 1977749791 2006158649 + 2141408799 49532520 64643108 79385615 96062769 273726379 564565671 8551 + 41035 906706094 988546669 1018231313 1032696425 1197507444 13312500..." + ... ... + ... ... + +The current release of MayaChemTools generates the following types of extended connectivity +fingerprints vector strings: + + FingerprintsVector;ExtendedConnectivity:AtomicInvariantsAtomTypes:Radi + us2;60;AlphaNumericalValues;ValuesString;73555770 333564680 352413391 + 666191900 1001270906 1371674323 1481469939 1977749791 2006158649 21414 + 08799 49532520 64643108 79385615 96062769 273726379 564565671 85514103 + 5 906706094 988546669 1018231313 1032696425 1197507444 1331250018 1338 + 532734 1455473691 1607485225 1609687129 1631614296 1670251330 17303... + + FingerprintsVector;ExtendedConnectivityCount:AtomicInvariantsAtomTypes + :Radius2;60;NumericalValues;IDsAndValuesString;73555770 333564680 3524 + 13391 666191900 1001270906 1371674323 1481469939 1977749791 2006158649 + 2141408799 49532520 64643108 79385615 96062769 273726379 564565671...;
