mProcess 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.
