Finally, the user is given the option to review the input and provide an arbitrary text label for this group of experiments, defaulting to the submission timestamp (shown in Fig. ). After selecting the appropriate "code" (i.e. an executable accessible by AiiDA on a local or networked computer, in this case the ketchup utility, which is part of tomato), the batch of experiments can be submitted. AiiDAlab then passes the specifications of the cells and protocols to AiiDA, which creates the appropriate nodes and digital twins, and manages the data retrieval without further action by the user.
