+**What it does**
+
+Extracts background ions (x-axis: RT; y-axis: Intensity) from 2D mass spectrometry data (LC/MS or GC/MS). The raw data is loaded from the open standard file formats (mzML, mzXML or mzData) and all of the individidual mass traces (M/Z +/- ppm over the whole scan range) are retrieved. A mass trace is retained when it is present in more than the given percentage of scans (option 'threshold').
+
+The resulting output file is in PeakML-format, containing a list of all the extracted background ions.
