After a run has completed you may wish to repeat the run and tweak some of the parameters. This is extremely easy to do. First make sure you are on the run page of the run you would like to clone. Next click the "Clone" button on the run page.
After you click the Clone button a dialogue will open up providing you with access to all the parameters of the experiment.
You can relaunch the protocol with the same parameters or change them to create a variation or use different input samples. Cloned runs will be launched in the same project as the original run.
