Summary
Aggregate and visualize mass spectrometry search results from multiple domain-specific MASST tools into unified, interactive outputs. This skill enables cross-domain metabolomics discovery by combining heterogeneous search outputs (from microbeMASST, plantMASST, tissueMASST, microbiomeMASST, foodMASST) through normalized data structures and interactive visualizations.
When to use
Use this skill when you have executed batch searches of MS/MS spectra against multiple domain-specific MASST indices and need to synthesize results across domains (e.g., comparing microbial vs. plant metabolite matches for the same query spectrum, or displaying matches distributed across tissue types and food sources simultaneously) into a single coherent view for interpretation or publication.
When NOT to use
- Input contains only single-domain results (e.g., only microbeMASST matches); use individual domain viewers instead
- Query spectra have not yet been searched against the domain-specific MASST indices; execute batch search first
- Analysis goal is domain-specific hypothesis testing rather than cross-domain discovery; individual domain tools may be more appropriate
Inputs
- MS/MS spectra in .mgf format (from MZmine or GNPS molecular networking)
- Universal Spectrum Identifiers (USIs) in .csv or .tsv format
- Domain-specific MASST search outputs in JSON and TSV format (one per domain: microbeMASST, plantMASST, tissueMASST, microbiomeMASST, foodMASST)
- GNPS library matches in TSV format
- Per-domain match counts and dataset summaries
Outputs
- Interactive HTML tree files aggregating results across all domains
- Unified JSON representation of aggregated search results
- _matches.tsv: consolidated matches across all domain-specific MASSTs with metadata
- _library.tsv: deduplicated GNPS library matches enabling Level 2 MSI annotation
- _datasets.tsv: counts of unique samples matching query per indexed dataset
- _count_domain.tsv files: domain-specific match count summaries
How to apply
Execute batch searches via the Fast Search API against all indexed domain-specific MASST data to generate domain-specific JSON and TSV outputs. Route each domain's search results (matches, library annotations, dataset counts) into a unified aggregation layer that normalizes heterogeneous output schemas into a common data structure. Implement visualization components—interactive HTML trees, tabular summaries, and count matrices—that render the combined results, preserving domain-specific context while enabling cross-domain comparison. Validate end-to-end by confirming that all domain results are present, no matches are dropped during aggregation, and interactive elements (e.g., tree expansion, filtering) operate correctly across the full combined dataset.

Examples
python code/jobs.py # After populating jobs.py with entries: ("spectra.mgf", "results/batch1") with skip_existing=True; metadataMASST then generates results/batch1_microbe.html, results/batch1_plant.html, ..., results/batch1_matches.tsv, results/batch1_library.tsv, results/batch1_datasets.tsv
Evaluation signals
- All queried spectra produce cross-domain result sets in metadataMASST output with non-empty aggregated JSON and HTML trees
- Aggregated _matches.tsv contains entries from all domain-specific MASSTs without duplication or loss; row counts match sum of per-domain matches
- Interactive HTML trees render without JavaScript errors and allow expansion/collapse of domain-specific result nodes
- Library-level annotations in _library.tsv are deduplicated and MSI Level 2 compliant (matched against GNPS libraries)
- _count_domain.tsv files show consistent totals when summed across domains and match individual domain search reports
Limitations
- Some Fast Search API requests may fail on first execution; re-runs with skip_existing=True are required to capture all possible matches across all domains
- Requires Python 3.10 to run batch search pipeline; compatibility with other Python versions not validated
- Visualization performance may degrade with very large numbers of matches (>10,000) across multiple domains; pagination or filtering strategies may be needed
- Results reflect only currently indexed data in GNPS/MassIVE, Metabolomics Workbench, Metabolights, and NORMAN; older or private datasets are not included
