Summary The choice of fragmentation strategies used during mass-spectrometry-based data acquisition directly affects the quality and coverage of subsequent structural identification – a crucial step in untargeted metabolomics data analysis. However, developing novel fragmentation strategies is challenging due to the high experimental cost of running an actual mass spectrometry instrument and the lack of a programmable simulation environment to support their development. ViMMS 2.0 is a software framework that can be used to develop new fragmentation strategies in metabolomics completely in-silico as well as on mass spectrometry instruments. The framework allows users to generate chemical objects (produced synthetically or extracted from existing mzML files) and simulate a tandem mass spectrometry process, where different fragmentation strategies can be rapidly implemented, tested and evaluated. In this paper, we present ViMMS 2.0, highlighting the software design choices of the framework and illustrate with an example how a new fragmentation strategy could be implemented in ViMMS 2.0.
