MALDI-imaging data acquisition workflow. MALDI-imaging data acquisition workflow and data representation as a datacube or a hyperspectral image with spatial coordinates x and y and with the mass spectral coordinate m/z. For every pair of coordinates (x, y) one gets a mass spectrum, for every m/z-value one gets an m/z-image. The so-called jet colormap from blue (lowest intensity) to yellow to red (highest intensity) was used for m/z-images.
