Scan mode

Region of interest (pixels) run step 1 first

X –

Y –

Step 1 generates a pixel grid — use it to pick your region.

◉ ROI active — steps 4–7 use selected pixels.
Steps 1–3 always use the full scan.

Browse spectrum

See energy ranges — generates pixel grid for ROI selection

full scan · set ROI after this step

Check energy resolution

Measure ZLP FWHM — data quality check

full scan

Correct ZLP drift

Shift each pixel's spectrum to 0 eV — aligns energy axis

full scan (correction must be global)

Detect edges

Auto-find edges from ROI mean spectrum

◉ uses ROI

Verify background fit

Confirm power-law windows on ROI mean spectrum

◉ uses ROI

Elemental map

Background-subtracted intensity — full edge window overview

◉ uses ROI

Peak intensity map

S-G smooth → detect peak → integrate ±5 eV — chemically specific

◉ uses ROI

Export data

Download CSV for ROI pixels — Origin / Excel

◉ uses ROI

Preview pattern

Log-stretched display · spot / ring / amorphous classification

Find true centre

Direct beam centroid (no-beamstop file) or Friedel pair voting

Detect spots

Blob detection · d-spacings · Friedel pairs · annotated image

Search database

COD + Materials Project by composition · or use uploaded CIF

Simulate & match

pymatgen forward simulation · all zone axes · likelihood 0–100%

Assign Miller indices

hkl labels on each spot · zone axis · publication figure

Electrochemistry Voltammetry · Impedance · Transference

ΔV (mV)

Iss window (s)

Leave blank → auto-detected from data after Step 1. Override to use a fixed value. Tool finds _01_PEIS, _02_MB, _03_PEIS files automatically.

Preview CA (I vs t)

Plot current vs time — verify I₀ and Iss

Preview EIS Nyquist

Nyquist plots before & after — verify Rp

Calculate σ

σ = L / (R₀ × A) — geometry from upload metadata

Calculate t⁺

Bruce-Vincent formula — needs CA + both PEIS files

ROUND-ROBIN STUDY Interlaboratory Reproducibility

Study ID:

Discover experiments

Walk folder tree — detect experiments by file content, not folder name

Analyse all nodes

Run selected workflow per experiment, apply cell geometry from condition file

Results table

ISO 5725 statistics — mean ± SD, CV%, Z-scores per lab

Generate plots

Build the selected chart type from cached results

Review fits

Nyquist grid — verify R_bulk intercepts used for conductivity
