1. Review the image: the centre panel shows detected particles as boxes. Toggle Show Binary Mask to inspect segmentation, Zoom to look closer, and Show IDs to label particles (hidden by default so they don't cover small rods).

2. Check the scale: the calibration source is shown at the top right. If it is wrong or uncalibrated, click Re-scale and draw a line along the scale bar, or use the Mask slider to fine-tune how aggressively touching particles are separated.

3. Curate the selection (right panel Ledger) — exclude clumps, dirt, or anything that isn't a clean rod:

• Click a particle on the image to deselect/reselect it (it flashes).
• Sort any column (e.g. Area ↓) to bring big clumps to the top.
• ⋮ on a row bulk-selects/deselects everything above or below it.
• Deselect outliers auto-removes statistical outliers (Tukey 1.5×IQR).

4. Update: press "Update Particles" to generate statistics and histograms from the kept particles.

5. Save & export:

• Download Excel / PDF: raw data and a report for this image.
• Add to Folder: confirms these results for the aggregate folder report.
