Once your experiment has successfully been completed, you can rerun it with different settings without having to set up the entire experiment from scratch. For that click on "Workspace" and then "My jobs". Find the experiment you would like to rerun and click on it. Inside the experiment click on "Open job configuration in BCCVL Job Composer". This will open a new window with the experiment set up as the previously. You can change as many settings as you like and run your experiment again.
