This manual page documents briefly the mineXpert software shipped within the msXpertSuite software suite.
This program can be used to load mass spectrometry data files and show the spectral data in a plot widget
for further analysis according to a variety of available integrations. While this program can operate
integrally in a graphical mode, it is also widely scriptable using JavaScript as a scripting language. A
typical data mining session would involve the following steps/actions:
• Open a mass spectrometry file and immediately compute a TIC chromatogram, show that chromatogram in
a dedicated window. If the data are from an ion mobility mass spectrometry experiment, compute a mz
= f(dt) color map. The TIC chromatogram and the color map are then the starting points for the
mining of the data.
• Perform a wide variety of integrations to a mass spectrum or a drift spectrum. Each new spectrum is
displayed in its dedicated window (the TIC chromatogram window, the Color map window, the Mass
spectrum window and the Drift spectrum window). Each new plot (be it a TIC chromatogram, a mass
spectrum or a drift spectrum) is potentially the start of another integration such that the
analysis can drill at each step further in the depth of the data.
• Perform isotopic cluster calculations and shape the obtained mass peak centroids into fully shaped
mass peaks (Gaussian or Lorentizan mathematical models).
• Each plot has specific functions associated to it: export as a (x,y) file, automatic recording of
the relevant data of signalled peaks into a file using a specific easy-to-understand grammar,
slicing of the data file into smaller data files.
• One feature of importance is the fact that a large part of the functionalities of the program are
scriptable (JavaScript) and a powerful scripting console is available to elaborate scripts before
storing them in script files to be automatically executed.
