A schematic showing the new standard PiMS Protocols for working with complexes (left-hand side) and an example of how Experiments based on these Protocols fit together to build up a workflow (right-hand side). Protocols specify the categories of Samples that are allowed as inputs and produced as outputs (colour-coded in the diagram). Experiments “snap together” by matching one output category to the next input category. By specifying identical input categories, a Protocol allows unrelated Samples of the same type to be combined, shown by the “Complexation” step in the example workflow.
