BARCC v8.02.000

This is a focused stability and reliability release that makes the Paint tool for custom regions fully trustworthy for quantitative work, plus a critical crash-prevention fix.

Highlights

Painted Region / Zone System Overhaul

  • Reliable zone registration: Regions you draw with the Paint tool and name immediately via right-click now correctly and consistently appear in the output spreadsheet when you click Count Cells.
  • Automatic paint stop + conversion: Count Cells now guarantees that paint mode is stopped and all strokes (explicitly named + auto-default "Painted Region N") are converted into countable zones.
  • Full state isolation: Every new TIFF loaded (via the left File Browser or Import) completely wipes previous masks, zone names, counters, and paint data. No more leakage between images.
  • Durable paint geometry: Strokes are now stored in stable model/image coordinates. They survive zooming, panning, and canvas refreshes.
  • Accurate interior counting:
    • Painted outlines now receive proper interior filling using scipy.ndimage.binary_fill_holes.
    • Cell-to-zone assignment uses a small neighborhood search around each centroid for tolerance.
  • No duplicate zones: Processed paint groups are retired after conversion, eliminating cases where 3 drawn regions would produce 6 entries.

Critical Stability Fix

  • Progress dialog safety: Closing the "Counting Cells" or "Detecting Cells" progress window with the X button (or Alt+F4) before the operation completes can no longer crash the entire application. All progress UI methods are now fully defensive.

Summary of Changes

These fixes primarily targeted long-standing fragile areas in the paint → named group → zone mask → counting pipeline that had caused:

  • "No regions defined" errors even after naming zones
  • Severe under-counting (e.g., 30 visible cells inside a region yielding only 1 count)
  • Duplicate zones in exports
  • Application crashes on early dialog dismissal during long operations

The Paint tool (for defining custom non-atlas regions) is now considered production-ready.

Other Notes

  • Blob Detection remains the default method (introduced in 8.01).
  • All previous automatic export behavior (.xlsx + _masked.tif) continues unchanged.
  • The User Manual has been fully updated for v8.02.000.

Requirements

For full .xlsx support with the Detection Parameters metadata sheet:

pip install openpyxl xlsxwriter

Full updated manual (BARCC_User_Manual.pdf) and source are included in the repository.

Previous release: See release-notes-v8.01.000.md for the Blob Detection, Smart Suggest, File Browser, and export features introduced in 8.01.000.
