Braggsight support

Keep the source beside the conclusion

Braggsight works offline and opens with a complete silicon demonstration pattern so every primary workflow can be reviewed without an external file.

Import a pattern

Choose the folder-plus button and select a UTF-8 or Latin-1 text or CSV file with angle and intensity columns. A single textual header is accepted.

Preserve a run

Use Projects to name the specimen and record the operator, instrument, preparation, and run note. Duplicate a run before testing a different analysis approach.

Review import quality

Open Pattern and inspect the quality audit. Braggsight reports excluded rows, duplicate angles, reordered acquisition data, irregular step spacing, negative intensities, and unusually flat signals. It preserves the original imported bytes and their SHA-256 fingerprint.

Compare raw and processed evidence

Use the Raw acquisition and Processed evidence segmented control. Smoothing defaults to zero. Baseline estimation can be disabled, and the processing settings remain with the saved run.

Calibrate peak position

In Calibration, enter a measured standard peak and its expected 2-theta position. Braggsight applies measured minus expected as an explicit zero-shift correction while preserving raw angles.

Enter instrumental broadening

Record the instrument FWHM and radiation wavelength. The app reports observed width and, when resolvable, square-root broadening correction. Scherrer size is withheld when the observed width does not exceed the entered instrument width.

Select and annotate peaks

Open Peak Review to include or exclude each detected peak and add an annotation. The report includes selected peaks only, while the project retains the full analysis.

Use reference screening responsibly

Reference scores compare selected peak positions with a small transparent set and are not phase identification. Confirm conclusions with suitable standards, calibrated instrumentation, full-pattern refinement, and a validated structure database.

Build an evidence bundle

Open Report and choose Build and share evidence bundle. The bundle contains a readable PDF, untouched raw CSV, processed CSV, selected-peaks CSV, and JSON manifest with source hash, context, settings, QC findings, results, and method URLs.

Recovering local data

The workspace uses atomic file writes and keeps one local recovery backup. If the primary document is unreadable, Braggsight attempts to restore the backup. Export important completed records to a destination you control.

Before reporting a problem

Include the Braggsight version, iOS or iPadOS version, device model, import format, screen involved, and exact steps. Share a JSON manifest only after confirming that its specimen and operator fields contain no sensitive information.
