Eels Edge Id

eels-edge-id

Scope

Identifies core-loss edges in EELS spectra, fits fine structure, and fingerprints oxidation states against a reference library. Returns candidate assignments with confidence intervals.

Expects standard EELS data products (image stacks, spectra or session directories as appropriate) with pixel size / dispersion recorded in the file metadata. Out of scope: acquisition scheduling, sample preparation, and any analysis outside the spectrum analysis stage of the workflow.

Safety

Read-only — no instrument control. The skill reads data from disk and returns results; it never moves the stage, changes dose, or alters column settings.

Usage

{
  "tool": "identify_edges",
  "arguments": {
    "input": "/data/eels/session-001",
    "output": "/data/eels/session-001/identify_edges"
  }
}

Returns a JSON object with ok, a result payload carrying the primary measurement or map, and diagnostics with per-item confidence. Units are SI unless stated otherwise in the result schema.

Reproducibility
