MatchMass: A Web-Based Tool for Efficient Mass Spectrometry Data Analysis

MatchMass is a user-friendly web-based application designed to streamline the analysis of mass spectrometry (MS) data for researchers studying complex mixtures of molecules. Users upload experimental data (m/z and abundance) and a list of theoretical monoisotopic masses. MatchMass then identifies matching molecules within the sample based on user-defined parameters (mass accuracy, abundance threshold, and ions of interest). The tool generates a visual comparison of experimental and theoretical m/z values, facilitates result exploration, and allows download of comprehensive reports. MatchMass eliminates the need for manual data processing, improving efficiency and accuracy in MS data analysis, particularly for researchers working with complicated mixtures.
