}

EM clusterer = new EM();
 clusterer.buildClusterer(dataClusterer);

// generate data for clusterer (w/o class)
 Remove filter = new Remove();
 filter.setAttributeIndices("" + (data.classIndex() + 1));
 try {
   filter.setInputFormat(data);
 } catch (Exception e) {
   e.printStackTrace();
 }
 Instances dataClusterer = Filter.useFilter(data, filter);
 // train clusterer
 EM clusterer = new EM();
 // set further options for EM, if necessary...
 // clusterer.setNumClusters(maxNumofClusters); //-1 for n number of clusters
 clusterer.buildClusterer(dataClusterer);

clusterer.buildClusterer(transposed);

Javadoc

Generates a clusterer. Has to initialize all fields of the clusterer that are not being set via options.
