Class Compare

java.lang.Object
chemaxon.clustering.Common
chemaxon.clustering.Compare
@PublicApi public class Compare extends Common
Compares two sets of objects (like compound libraries) using diversity and dissimilarity calculations.
This class can be used from command-line or from the API.
See the documentation for details.

An example for running Compare: 


 ConnectionHandler ch;
 String selectString1;
 String selectString2;
 ...
 Compare cp=new Compare();
 cp.setInput1(ch, selectString1 );
 cp.setInput2(ch, selectString2 );
 cp.setOutput(System.out);
 cp.setDimensions(0);
 cp.setFpSize(512);
 cp.setStatNeeded(true);
 cp.setOnlyStat(false);
 cp.setStatStream(System.out);
 cp.setIdGeneration(true);
 cp.setThreshold(0.1f);
 cp.setOnlyDissimilarListed(true);
 cp.setDifferentIdsOnly(true);
 cp.run();
