Polydisperse analysis

Open this window from the right-column polydisperse icon. While it stays open, new samples run Guinier → fit_sizes (D(R)) automatically. Closing the window disarms that chain. Guinier here is independent of the monodisperse window and is stored under guinier_poly/.

Each analysis pane shows plots, a Passport table, and Adjust (controls live in wizards). Optional MIXTURE modeling is launched with Start modeling into a separate Distribution Modeling app — press Confirm there to run.

Polydisperse Guinier quality is often poor; that is expected and does not feed fit_sizes as a hard constraint. Parameter edits (and confirming an Adjust wizard) pause auto-processing until you Resume auto-processing (Ctrl+P; Ctrl+X stops auto).

Polydisperse analysis window

Layout

Guinier — independent display / passport / Adjust (same style as monodisperse Guinier).
GNOM D(R) — I(q) and D(R) plots, quality Passport, and Adjust (opens the D(R) / GNOM wizard).
D(R) mixture pane — None / MIXTURE; Start modeling; I(q) / Distribution previews after a MIXTURE run. (Older “Re-run D(R)” remains available for a sizes-only re-fit of the current profile.)
Global — Stop auto-processing / Resume auto-processing (Ctrl+X / Ctrl+P).

Recipes

To arm polydisperse analysis

Main window right → polydisperse icon → window opens (armed while open).

Main window with analysis icons

To adjust Guinier (poly)

Click Adjust under the Guinier passport → edit first/last → Confirm. This does not pin fit_sizes; it only refreshes the poly Guinier display / guinier_poly/ artifacts.

To adjust D(R) / fit_sizes

Click Adjust (or either embedded GNOM plot) → edit q-range / rmin / rmax / alpha and boundary checkboxes in the wizard. Plots and passport update live; press Confirm to write parameters and re-run fit_sizes (pinned Rmax refine). Opening the wizard alone does not pause the queue — the first control change does. Use Restore auto to return to the last auto-fit snapshot. Click a wizard plot to open an enlarged viewer (matplotlib toolbar + title-bar maximize). Then Resume auto-processing when ready.

D(R) / GNOM adjust wizard

To enable MIXTURE

Under the mixture pane, choose MIXTURE (vs None) → Start modeling → Distribution Modeling app opens → Confirm there to run model_mixture. When that app is open and auto is on, finishing D(R) can prompt Confirm on the modeling app.

Polydisperse window with MIXTURE selected

To browse MIXTURE results (advanced viewer)

In the Distribution Modeling app, after a successful MIXTURE run, click the Distribution plot to open the advanced MIXTURE viewer (model combo, mixture + component previews, BIC_χ²). Left-column component thumbnails select the large view only (they do not open a separate window). Click the large plot to enlarge further (title-bar maximize).

MIXTURE advanced results viewer

To pause or resume the auto chain

Stop auto-processing (Ctrl+X) → Resume auto-processing (Ctrl+P) when ready.

Outputs (per sample)

guinier_poly/<stem>/ — Guinier region YAML
fit_sizes/<stem>/ — GNOM .out, D(R) CSV, quality YAML
mixture/<stem>/ — per-model dirs, mixture_results.csv (when MIXTURE has run)
