While the current filters address many annotation inaccuracies, they currently still lack plausibility checks that consider both metadata and measured fragments. Wrong chemical annotations that are consistent with the measured mass, for instance, will go unnoticed in the current pipeline. Future expansions might include filters that check if the fragments match the given annotation. Additionally, we note that future use cases may rely on other metadata fields that are not yet cleaned by the current matchms filters. For instance, the instrument type or collision energies could be important fields that might require additional standardization. The modular and flexible structure of matchms makes it straightforward to add such filters to the matchms pipeline in the future.
