CorrectOverloadedPeaks

Correct Overloaded Peaks from GC-APCI-MS Data

Analyzes and modifies metabolomics raw data (generated using Gas Chromatography-Atmospheric Pressure Chemical Ionization-Mass Spectrometry) to correct overloaded signals, i.e. ion intensities exceeding detector saturation leading to a cut-off peak. Data in 'xcmsRaw' format are accepted as input and 'mzXML' files can be processed alternatively. Overloaded signals are detected automatically and modified using an Gaussian or an Isotopic-Ratio approach. Quality control plots are generated and corrected data are stored within the original 'xcmsRaw' or 'mzXML' respectively to allow further processing.
