Although primarily focused on proteomics, the PSI does reach out to, and has members from the metabolomics and lipidomics communities to extend the use of PSI standards for metabolomics applications, with substantial success for mzML and mzTab-M, and good future perspectives for USI and mzSpeclib. In this context, the PSI also fosters collaboration with computational-focused groups, such as the CompMS group (), which promotes the development of computational mass spectrometry algorithms and training in their use. The CompMS group includes participation from both proteomics and metabolomics researchers who use MS.
