Welcome to MatchMass, a powerful tool designed to streamline the analysis of mass spectrometry data. With MatchMass, you can quickly and accurately compare your experimental results against theoretical values, helping you identify the molecules and ions present in your samples with confidence.

Functions of Matchmass:
- Load tables containing experimental data and theoretical masses of molecules provided by user.
- Set the limits of matching by defining mass accuracy and minimum signal intensity (abundance) of interest.
- Generate mass-to-charge (m/z) values of ions of interest from the provided theoretical masses of neutral molecules.
- Provide two simple plots for visual check of matching settings and final results.
- Do the matching. This means finding and returning experimental values corresponding (within user-defined limits) to the molecules (ions) in the theoretical table.
- Generate excel file with detailed report and complete table and theoretical m/z values. - Users may download our dummy data to test MatchMass without having their own data.
