Overview
The spectrum-summary app displays peak and neutral-loss histograms for spectra selected through a GNPS2 network component or a list of Universal Spectrum Identifiers. It supports inspection of shared fragmentation evidence before more detailed annotation.
What can this tool do?
Common uses
- Inspect common fragment signals among related spectra.
- Examine recurring neutral losses in a selected network component.

Scope and considerations
Designed for
- Exploratory comparison of shared fragmentation across selected MS/MS spectra.
Not designed for
- Definitive structure identification or quantitative feature-table processing.
Important requirements
- Accessible spectra referenced by USIs or a supported GNPS network task.
- Selection of spectra appropriate to the scientific comparison.
Considerations
- Shared peaks and losses support hypotheses but are not unique structural assignments.
- Acquisition conditions, precursor selection and the chosen spectrum subset affect the summary.
- Input controls and plots were inspected without submitting a user dataset; operational performance remains untested.
Access and documentation
Public hosted interface; input spectra must be retrievable through the selected GNPS task or USI route. No source-code license or independent performance benchmark was verified.
Evidence and review
Official tool index and both public input screens reviewed on 2026-09-10. No dedicated publication identified; no general GNPS paper added as an app-specific publication. No private data uploaded or independent benchmark performed.
No dedicated scholarly publication is listed. Follow the official documentation and resource-specific citation guidance.
