Overview
Food Readout joins GNPS library matches to food metadata and ontology categories. It offers feature-level and group-level views of candidate food-associated signals, including abundance plots and exploratory statistical displays.
What can this tool do?
Common uses
- Explore food-associated annotations in nutrition or exposome studies.
- Inspect variation in candidate dietary markers across sample groups.
Scientific fit
Primary function
Visualization and reporting
Data compatibility
Inputs
Feature or peak table, Compound list or annotations, Sample metadata
Outputs
Compound list or annotations, Human-readable report, Statistical results
Input formats
CSV or TSV, Completed GNPS2 FBMN task ID
Output formats
Processed food tables and exportable box, PCA and volcano plots
Scope and considerations
Designed for
- Post-processing LC-MS/MS library matches in their food-related reference context.
Not designed for
- Measuring absolute food intake or proving recent consumption.
Important requirements
- A completed FBMN task with GNPS library matches, a feature quantification table and sample metadata.
- CSV/TSV tables with matching feature and sample identifiers.
Considerations
- Reference coverage is incomplete, and many compounds occur in food and non-food sources.
- Group differences require study-design and statistical review; an exploratory plot is not causal evidence.
