I want to save the clusterer (Cobweb) results to an arff file, but I can't seem to figure it out. I know how to save the results from GUI, but I cant figure out how to do it from my java code, even after searching for a couple of hours.

Here is my code. 

ArffLoader loader = new ArffLoader();
loader.setFile(new File(sourceFile));
Instances structure = loader.getStructure();

Cobweb cw = new Cobweb();
cw.buildClusterer(structure);
Instance current;
while ((current = loader.getNextInstance(structure)) != null)
     cw.updateClusterer(current);
cw.updateFinished();

Have you tried using

weka.filters.unsupervised.attribute.AddCluster

which adds the cluster assignment to your data.
