Heatmaps of the top 10 significant features obtained from data collected in the negative ion mode and positive ion mode from lipid and peptide ions. The hierarchical clustering dendrogram based on the lipid and peptide ions is presented under the heatmap of the multi-omics and the intensity of each feature can be read by the color scale located at the bottom left.
