To clone the whole experiment, in which all the tasks and protocol steps are copied, select the Copy as template action from the drop-down menu (see the image below). It is important to note that when you copy an experiment as a template, the results and comments are not included.
After selecting the action, a window opens where you have to select a project, to which you wish to copy the experiment. You can also choose to copy the experiment in the same same project (i.e. current project).
When you have successfully copied the experiment, select the Edit details action from the drop-down menu to change the name of the copied experiment.
