    // create the marshaller and check that the file is indexed
    MzMLUnmarshaller um = new MzMLUnmarshaller(mzMLFileUrl);
    assertTrue( um.isIndexedmzML() );

    // the checksum is not correct, so we skip this test
    // assertTrue(um.isOkFileChecksum());

    MzML content = um.unmarshall();
    assertNotNull(content);

    // fine the spectrum with id "index=0"
    List<Spectrum> spectrumList = content.getRun().getSpectrumList().getSpectrum();
    Spectrum spectrum = null;
    for (Spectrum sp : spectrumList) {
        assertNotNull(sp);
