MetaFIND screen shot. The MetaFIND Application. Upon selection of the reference feature from the Drop Down Menu (features yet to be examined are displayed in white font) the Correlation Graph displays positively and negatively correlated features from the imported list (black). Novel Recommended Features are also displayed (green). Feature values may be examined globally (Feature Heatmap) and for selected features (Feature Plot). In this example the features most highly correlated (r ≥ 0.92) to the Reference Feature represent the metabolite hippurate.
