29 <h2>DESCRIPTION</h2>
30 <p>ExtendedConnectivityFingerprints [ Ref 48, Ref 52 ] 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="#setneighborhoodradius">SetNeighborhoodRadius</a>
33 , <a href="#stringifyextendedconnectivityfingerprints">StringifyExtendedConnectivityFingerprints</a>
34 </p><p><strong>ExtendedConnectivityFingerprints</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>ExtendedConnectivityFingerprints</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>ExtendedConnectivityFingerprints</strong>
43 corresponding to following <strong>AtomtomIdentifierTypes</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>, <strong>AtomicInvariantsToUse</strong>
49 and <strong>FunctionalClassesToUse</strong>, initial atom types are assigned to all non-hydrogen atoms in
50 a molecule and these atom types strings are converted into initial atom identifier integers using
51 <strong>TextUtil::HashCode</strong> function. The duplicate atom identifiers are removed.</p>
52 <p>For <strong>NeighborhoodRadius</strong> value of <em>0</em>, the initial set of unique atom identifiers comprises
53 the molecule fingerprints. Otherwise, atom neighborhoods are generated for each non-hydrogen
54 atom up-to specified <strong>NeighborhoodRadius</strong> value. For each non-hydrogen central atom
55 at a specific radius, its neighbors at next radius level along with their bond orders and previously
56 calculated atom identifiers are collected which in turn are used to generate a new integer
57 atom identifier; the bond orders and atom identifier pairs list is first sorted by bond order
58 followed by atom identifiers to make these values graph invariant.</p>
59 <p>After integer atom identifiers have been generated for all non-hydrogen atoms at all specified
60 neighborhood radii, the duplicate integer atom identifiers corresponding to same hash code
61 value generated using <strong>TextUtil::HashCode</strong> are tracked by keeping the atom identifiers at
62 lower radius. Additionally, all structurally duplicate integer atom identifiers at each specified
63 radius are also tracked by identifying equivalent atom and bonds corresponding to substructures
64 used for generating atom identifier and keeping integer atom identifier with lowest value.</p>
65 <p>For <em>ExtendedConnnectivity</em> value of fingerprints <strong>Type</strong>, the duplicate identifiers are
66 removed from the list and the unique atom identifiers constitute the extended connectivity
67 fingerprints of a molecule.</p>
68 <p>For <em>ExtendedConnnectivityCount</em> value of fingerprints <strong>Type</strong>, the occurrence of each
69 unique atom identifiers appears is counted and the unique atom identifiers along with their
70 count constitute the extended connectivity fingerprints of a molecule.</p>
71 <p>For <em>ExtendedConnectivityBits</em> value of fingerprints <strong>-m, --mode</strong>, the unique atom identifiers
72 are used as a random number seed to generate a random integer value between 0 and <strong>--Size</strong> which
73 in turn is used to set corresponding bits in the fingerprint bit-vector string.</p>
74 <p>The current release of MayaChemTools generates the following types of extended connectivity
75 fingerprints vector strings:</p>
