Scope and considerations

Designed for

  • Find public spatial metabolomics datasets.

Not designed for

  • Treating a spatial annotation as complete isomer or stereochemical confirmation.

Important requirements

  • For new analyses, compatible imaging-MS data and acquisition metadata; browsing public results is a separate workflow.

Considerations

  • Review annotation confidence, adduct assumptions and database choice; spatial colocalization does not by itself imply a biological interaction.

Access and documentation

Public platform with Apache-2.0 source code; dataset access and reuse depend on the individual deposit.
