Edax Phase Map

edax-phase-map

Scope

Super-resolution phase mapping from energy dispersive spectra. Performs automatic peak deconvolution, background subtraction, and ZAF quantification, returning per-pixel elemental fractions plus a labelled phase map.

Expects standard EDS 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": "phase_map",
  "arguments": {
    "input": "/data/eds/session-001",
    "output": "/data/eds/session-001/phase_map"
  }
}

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

Runtime: python 3.10. Pin dependencies in requirements.txt / package.json and run with a fixed seed. Reviewers can reproduce the reported numbers with:

cd skills/edax-phase-map
pip install -r requirements.txt && python3 verify.py --fixture fixtures/sample --seed 0
