Make sure that the experiment configuration is stored in the DDBB for every run

Hi @ltenorio , as we discussed right now, we have to make sure that for every experiment run, the configuration is stored in the DDBB for provenance and reproducibility

On the other hand, even if it's stored, I think there's no way to visualize these configurations with the API nor with the GUI, right?
