In the following, we assume that the experimental group uses an electronic lab notebook (ELN) to collect and store all experimental data on a particular sample. We demonstrate how such an ELN can be connected to a simulation platform that gives easy access to routine but state-of-the-art simulations. Such a connection ensures that experimental results can be compared to simulations on a routine basis. We have chosen the cheminfo ELN as the ELN and AiiDAlab 6 as the simulation platform. Both platforms are open-source and allow storing data provenance, meaning that we have a complete record of how simulations and experiments have been performed and influenced each other. The cheminfo ELN makes sure that all required data are sent to AiiDAlab along with the request for a simulation. Once the simulations are done, the results are automatically linked to the sample and interactively visualised in a web browser. The results contain metadata and the unique identifiers of the calculations, enabling users to trace back at a later time the full provenance of their simulations performed by AiiDAlab.
