how to save clusterer model into arff or csv file (WEKA JAVA)

Question

Is there any way to do so? I know how to save the cluster model , but not sure how to save arff file.Thanks for the help.

Answer 1

 Instances dataSet = getInstancesSomePlace();
 ArffSaver saver = new ArffSaver();
 saver.setInstances(dataSet);
 saver.setFile(new File("./data/test.arff"));
 saver.setDestination(new File("./data/test.arff"));   
 saver.writeBatch();

I used this form to save the clustering result in an data.arrf https://weka.wikispaces.com/Save+Instances+to+an+ARFF+File
