Overview
The GNPS2 MassQL Analysis app combines spectral-library query exploration with assisted query construction. It is distinct from the local-file MassQL Playground and from the underlying MassQL language.
What can this tool do?
Common uses
- Explore fragmentation queries against MS/MS spectral libraries.
- Draft or explain a MassQL query with the app's LLM assistance.
Scientific fit
Primary function
Spectral processing and comparison
Data compatibility
Inputs
Mass spectra
Outputs
Human-readable report
Input formats
MassQL query text and spectral-library selections through the hosted interface
Output formats
Interactive query results and query explanations; export formats not verified
Scope and considerations
Designed for
- Interactive library-query exploration and learning MassQL syntax.
Not designed for
- Treating generated query text or a library hit as a validated identification.
Important requirements
- Internet access and the hosted app; check requirements for assisted features.
Considerations
- Inspect generated queries, tolerances and selected libraries before interpreting matches.
- The reviewed documentation does not establish model accuracy or guarantee export compatibility.
- Do not assume the hosted app shares the local-file privacy properties of MassQL Playground.
Access and documentation
Publicly listed hosted GNPS2 interface. Availability, account requirements and LLM-service limits should be checked in the app; no software or data license is inferred from hosted access.
