Gel view comparing the M. massiliensis NP3T spectrum with those of M. micronuciformis and Veillonella species. The Gel View displays the raw spectra of all loaded spectrum files arranged in a pseudo-gel like look. The x-axis records the m/z value. The left y-axis displays the running spectrum number originating from subsequent spectra loading. The peak intensity is expressed by a Gray scale scheme code. The color bar and the right y-axis indicate the relation between the color a peak is displayed and the peak intensity in arbitrary units.
