  "Description": "Provides tools for assigning molecular formulas from exact\nmasses obtained by ultrahigh-resolution mass spectrometry. The\nmethodology follows the workflow described in Leefmann et al.\n(2019) <doi:10.1002/rcm.8315>. The package supports the\ninspection, filtering and visualization of molecular formula\ndata and includes utilities for calculating common molecular\nparameters (e.g., double bond equivalents, DBE). A graphical\nuser interface is available via the 'shiny'-based 'ume'\napplication.",
