20 <h2>NAME</h2>
21 <p>MACCSKeys</p>
22 <p>
23 </p>
24 <h2>SYNOPSIS</h2>
25 <p>use Fingerprints::MACCSKeys;</p>
26 <p>use Fingerprints::MACCSKeys qw(:all);</p>
27 <p>
28 </p>
29 <h2>DESCRIPTION</h2>
30 <p><strong>MACCSKeys</strong> [ Ref 45-47 ] class provides the following methods:</p>
31 <p> <a href="#new">new</a>, <a href="#generatefingerprints">GenerateFingerprints</a>, <a href="#generatemaccskeys">GenerateMACCSKeys</a>, <a href="#getdescription">GetDescription</a>, <a href="#setsize">SetSize</a>, <a href="#settype">SetType</a>
32 , <a href="#stringifymaccskeys">StringifyMACCSKeys</a>
33 </p><p><strong>MACCSKeys</strong> is derived from <strong>Fingerprints</strong> class which in turn is derived from
34 <strong>ObjectProperty</strong> base class that provides methods not explicitly defined in <strong>MACCSKeys</strong>,
35 <strong>Fingerprints</strong> or <strong>ObjectProperty</strong> classes using Perl's AUTOLOAD functionality. These
36 methods are generated on-the-fly for a specified object property:</p>
37 <div class="OptionsBox">
38 Set&lt;PropertyName&gt;(&lt;PropertyValue&gt;);
39 <br/> $PropertyValue = Get&lt;PropertyName&gt;();
40 <br/> Delete&lt;PropertyName&gt;();</div>
41 <p>For each MACCS (Molecular ACCess System) keys definition, atoms are processed to
42 determine their membership to the key and the appropriate molecular fingerprints strings
43 are generated. An atom can belong to multiple MACCS keys.</p>
44 <p>For <em>MACCSKeyBits</em> value of <strong>Type</strong> option, a fingerprint bit-vector string containing
45 zeros and ones is generated and for <em>MACCSKeyCount</em> value, a fingerprint vector string
46 corresponding to number of MACCS keys [ Ref 45-47 ] is generated.</p>
47 <p><em>MACCSKeyBits or MACCSKeyCount</em> values for <strong>Type</strong> along with two possible
48 <em>166 | 322</em> values of <strong>Size</strong> supports generation of four different types of MACCS
49 keys fingerprint: <em>MACCS166KeyBits, MACCS166KeyCount, MACCS322KeyBits, MACCS322KeyCount</em>.</p>
50 <p>The current release of MayaChemTools generates the following types of MACCS keys
51 fingerprints bit-vector and vector strings:</p>
