29 <h2>DESCRIPTION</h2>
30 <p><strong>AtomNeighborhoodsFingerprints</strong> [ Ref 53-56, Ref 73 ] class provides the following methods:</p>
31 <p> <a href="#new">new</a>, <a href="#generatefingerprints">GenerateFingerprints</a>, <a href="#getdescription">GetDescription</a>, <a href="#setatomidentifiertype">SetAtomIdentifierType</a>
32 , <a href="#setatomicinvariantstouse">SetAtomicInvariantsToUse</a>, <a href="#setfunctionalclassestouse">SetFunctionalClassesToUse</a>, <a href="#setmaxneighborhoodradius">SetMaxNeighborhoodRadius</a>
33 , <a href="#setminneighborhoodradius">SetMinNeighborhoodRadius</a>, <a href="#stringifyatomneighborhoodsfingerprints">StringifyAtomNeighborhoodsFingerprints</a>
34 </p><p><strong>AtomNeighborhoodsFingerprints</strong> is derived from <strong>Fingerprints</strong> class which in turn
35 is derived from <strong>ObjectProperty</strong> base class that provides methods not explicitly defined
36 in <strong>AtomNeighborhoodsFingerprints</strong>, <strong>Fingerprints</strong> or <strong>ObjectProperty</strong> classes using Perl's
37 AUTOLOAD functionality. These methods are generated on-the-fly for a specified object property:</p>
38 <div class="OptionsBox">
39 Set&lt;PropertyName&gt;(&lt;PropertyValue&gt;);
40 <br/> $PropertyValue = Get&lt;PropertyName&gt;();
41 <br/> Delete&lt;PropertyName&gt;();</div>
42 <p>The current release of MayaChemTools supports generation of <strong>AtomNeighborhoodsFingerprints</strong>
43 corresponding to following <strong>AtomIdentifierTypes</strong>:</p>
44 <div class="OptionsBox">
45 AtomicInvariantsAtomTypes, DREIDINGAtomTypes, EStateAtomTypes,
46 <br/> FunctionalClassAtomTypes, MMFF94AtomTypes, SLogPAtomTypes,
47 <br/> SYBYLAtomTypes, TPSAAtomTypes, UFFAtomTypes</div>
48 <p>Based on the values specified for <strong>AtomIdentifierType</strong> along with other specified
49 sucb as <strong>AtomicInvariantsToUse</strong> and <strong>FunctionalClassesToUse</strong>, initial atom types are
50 assigned to all non-hydrogen atoms in a molecule. Using atom neighborhoods
51 around each non-hydrogen central atom corresponding to radii between specified values
52 <strong>MinNeighborhoodRadius</strong> and <strong>MaxNeighborhoodRadius</strong>, unique atom types at each radii
53 level are counted and an atom neighborhood identifier is generated.</p>
54 <p>The format of an atom neighborhood identifier around a central non-hydrogen atom at a
55 specific radius is:</p>
56 <div class="OptionsBox">
57 NR&lt;n&gt;-&lt;AtomType&gt;-ATC&lt;n&gt;</div>
58 <div class="OptionsBox">
59 NR: Neighborhood radius
60 <br/> AtomType: Assigned atom type
61 <br/> ATC: Atom type count</div>
62 <p>The atom neighborhood identifier for non-hydrogen central atom corresponding to all specified radii
63 is generated by concatenating neighborhood identifiers at each radii by colon as a delimiter:</p>
64 <div class="OptionsBox">
65 NR&lt;n&gt;-&lt;AtomType&gt;-ATC&lt;n&gt;:NR&lt;n&gt;-&lt;AtomType&gt;-ATC&lt;n&gt;:...</div>
66 <p>The atom neighborhood identifiers for all non-hydrogen central atoms at all specified radii are
67 concatenated using space as a delimiter and constitute atom neighborhood fingerprint of the molecule.</p>
68 <p>The current release of MayaChemTools generates the following types of atom neighborhoods
69 fingerprints vector strings:</p>
