 * data files are structured in different ways and the software for mass data
 * format conversion from raw files to mzML or mzXML produce mass data
 * characterized by different behaviours.
 *
 * The different characteristics of mass spectrometry data set are:
 *
 * The size of the various mass spectra in the file is constant or variable;
 *
 * The first m/z value of the various spectra is identical or not (that is,
 * the spectra are root in a constant or variable root m/z value);
 *
 * The m/z delta between two consecutive m/z values of a given spectrum are
 * constant or variable;
 *
 * The spectra contain or not 0-value m/z data points;
