GNPS2 Network Overlay

Attach custom feature attributes to an existing GNPS2 molecular network using matching node identifiers.

Overview

The network-overlay workflow joins an uploaded feature table to a completed network. The documented Progenesis route launches it from FBMN and supplies the existing spectra and graph automatically. The overlay adds supplied attributes; it does not independently establish their biological meaning.

What can this tool do?

Scope and considerations

Designed for

  • Overlaying table attributes on existing GNPS2 network nodes.

Not designed for

  • Generating new measured evidence or validating uploaded annotations.

Important requirements

  • A completed network, its spectra and a compatible overlay table.
  • A node-ID column that matches network identifiers; follow the documented column-header restrictions.

Considerations

  • Mismatched identifiers can prevent correct attribute assignment.
  • The linked tutorial demonstrates Progenesis/FBMN; no broader format support was independently tested.
  • The source repository linked from the workflow collection could not be retrieved during review.
