29 <h2>DESCRIPTION</h2> | |
30 <p><strong>TopologicalPharmacophoreAtomPairsFingerprints</strong> [ Ref 60-62, Ref 65, Ref 68 ] class provides | |
31 the following methods:</p> | |
32 <p>new, GenerateFingerprints, GetDescription, GetAtomPairIDs, SetAtomTypesToUse, | |

35 SetNormalizationMethodology, SetValuesPrecision, | |
36 StringifyTopologicalPharmacophoreAtomPairsFingerprints</p> | |
37 <p><strong>TopologicalPharmacophoreAtomPairsFingerprints</strong> is derived from <strong>Fingerprints</strong> class which in turn | |
38 is derived from <strong>ObjectProperty</strong> base class that provides methods not explicitly defined | |
39 in <strong>TopologicalPharmacophoreAtomPairsFingerprints</strong>, <strong>Fingerprints</strong> or <strong>ObjectProperty</strong> classes using Perl's | |
40 AUTOLOAD functionality. These methods are generated on-the-fly for a specified object property:</p> | |
41 <div class="OptionsBox"> | |
42 Set<PropertyName>(<PropertyValue>); | |
43 <br/> $PropertyValue = Get<PropertyName>(); | |
44 <br/> Delete<PropertyName>();</div> | |
45 <p>Based on the values specified for <strong>AtomTypesToUse</strong>, pharmacophore atom types are | |
46 assigned to all non-hydrogen atoms in a molecule and a distance matrix is generated. | |
47 A pharmacophore atom pairs basis set is initialized for all unique possible pairs within | |
48 <strong>MinDistance</strong> and <strong>MaxDistance</strong> range.</p> | |
49 <div class="OptionsBox"> | |
50 Let:</div> | |
51 <div class="OptionsBox"> | |
52 P = Valid pharmacophore atom type</div> | |
53 <div class="OptionsBox"> | |
54 Px = Pharmacophore atom type x | |
55 <br/> Py = Pharmacophore atom type y</div> | |
56 <div class="OptionsBox"> | |
57 Dmin = Minimum distance corresponding to number of bonds between two atoms | |
58 <br/> Dmax = Maximum distance corresponding to number of bonds between two atoms | |
59 <br/> D = Distance corresponding to number of bonds between two atoms</div> | |
60 <div class="OptionsBox"> | |
61 Px-Dn-Py = Pharmacophore atom pair ID for atom types Px and Py at distance Dn</div> | |
62 <div class="OptionsBox"> | |
63 P = Number of pharmacophore atom types to consider | |
64 <br/> PPDn = Number of possible unique pharmacophore atom pairs at a distance Dn</div> | |
65 <div class="OptionsBox"> | |
66 PPT = Total number of possible pharmacophore atom pairs at all distances between Dmin and Dmax</div> | |
67 <div class="OptionsBox"> | |
68 Then:</div> | |
69 <div class="OptionsBox"> | |
70 PPD = (P * (P - 1))/2 + P</div> | |
71 <div class="OptionsBox"> | |
72 PPT = ((Dmax - Dmin) + 1) * ((P * (P - 1))/2 + P) | |
73 <br/> = ((Dmax - Dmin) + 1) * PPD</div> | |
74 <div class="OptionsBox"> | |
75 So for default values of Dmin = 1, Dmax = 10 and P = 5,</div> | |
76 <div class="OptionsBox"> | |
77 PPD = (5 * (5 - 1))/2 + 5 = 15 | |
78 <br/> PPT = ((10 - 1) + 1) * 15 = 150</div> | |
79 <div class="OptionsBox"> | |
80 The pharmacophore atom pairs bais set includes 150 values.</div> | |
81 <div class="OptionsBox"> | |
82 The atom pair IDs correspond to:</div> | |
83 <div class="OptionsBox"> | |
84 Px-Dn-Py = Pharmacophore atom pair ID for atom types Px and Py at distance Dn</div> | |
85 <div class="OptionsBox"> | |
86 For example: H-D1-H, H-D2-HBA, PI-D5-PI and so on</div> | |
87 <p>Using distance matrix and pharmacohore atom types, occurrence of unique pharmacohore atom | |
88 pairs is counted. The contribution of each atom type to atom pair interaction is optionally | |
89 weighted by specified <strong>AtomTypesWeight</strong> before assigning its count to appropriate distance | |
90 bin. Based on <strong>NormalizationMethodology</strong> option, pharmacophore atom pairs count is optionally | |
91 normalized. Additionally, pharmacohore atom pairs count is optionally fuzzified before or after | |
92 the normalization controlled by values of <strong>FuzzifyAtomPairsCount</strong>, <strong>FuzzificationMode</strong>, | |
93 <strong>FuzzificationMethodology</strong> and <strong>FuzzFactor</strong>.</p> | |
94 <p>The final pharmacophore atom pairs count along with atom pair identifiers involving all non-hydrogen | |
95 atoms, with optional normalization and fuzzification, constitute pharmacophore topological atom pairs | |
96 fingerprints of the molecule.</p> | |
97 <p>For <em>ArbitrarySize</em> value of <strong>AtomPairsSetSizeToUse</strong>, the fingerprint vector correspond to | |
98 only those topological pharmacophore atom pairs which are present and have non-zero count. However, | |
99 for <em>FixedSize</em> value of <strong>AtomPairsSetSizeToUse</strong>, the fingerprint vector contains all possible | |
100 valid topological pharmacophore atom pairs with both zero and non-zero count values.</p> | |
101 <p>The current release of MayaChemTools generates the following types of topological pharmacophore | |

310 are incremented by PPxyDn * 0.15.</p> | |
311 <p>And during <em>FuzzyBinSmoothing</em> the occurrence counts at Distance Dn is scaled back using multiplicative | |
312 factor of (1 - 2*0.15) and the occurrence counts at distances Dn -1 and Dn + 1 are incremented by | |
313 PPxyDn * 0.15. In other words, occurrence bin count is smoothed out by distributing it over the | |
