11. Virtual Lab AMsterdam Process Flow Template (PFT) Used as a blueprint for a specific type of experiments PFT is designed offline by the experts in each scientific domain It is the main interface used by the VLAM-G users to perform a specific experimentation in the VLAM-G environment. It Guides the user while performing the experiment.
