ShinyTPs was also applied to curate TP information for a list of 436 tentatively identified compounds (see Table ) from a Luxembourgish wastewater treatment plant sample. These tentatively identified compounds were used as inputs to ShinyTPs to curate associated TP information using the "Transformation reaction curation" tab, totalling 645 new reactions associated with 496 compounds. Of these reactions, 319 were not listed for any biosystem in PubChem. The PubChem Transformations library with and without the addition of the new reactions was then used to perform a TP suspect screening in patRoon with the same sample. In total, 72 compounds out of the 436 were labelled as TPs using the TP suspect lists. Out of these, 18% were only detected after curation with ShinyTPs (see Figure .) Thus, the additional curation of TPs using ShinyTPs contributed to the number of tentatively identified TPs in this study and demonstrates that expanding the libraries will help support non-target analysis workflows in the community.
