Gel view comparing Holdemania massiliensis strain AP2T, Solobacterium moorei, Erysipelothrix tonsillarum, E. rhusiopathiae, E. inopinata and Bulleida exctructa. The gel view displays the raw spectra of 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 as a gray scale. The color bar and the right y-axis indicate the relation between the color with which a peak is displayed and the peak intensity in arbitrary units. Displayed species are indicated on the left.
