public class RunExperiment

extends java.lang.Object

RunExperiment is the class to activate the experiment progress. Create the RunExperiment and call RunExperiment.go() to start the experiment. The go method utilizes SwingWorker class to handle the time-comsuming experiment running that is controlled by the inner class execExperiment so the GUI could remain responsive.
