Cohort Dashboard · Built into QuPath

Every image. Every validator.
One glance.

The qTrace Dashboard displays real-time QA status across your entire QuPath project. Filter, search, and inspect any .qtrace passport without leaving QuPath.

Cohort overview

All .qtrace files from your project in one table — sample, ROI, region, BV/Tau counts, validation status, alignment, segmentation steps, classifiers, and total step count.

Multi-axis filters

Filter simultaneously by contributor, annotation class, validation state, BV/Tau presence, and project. Filters stack — drill down to exactly the subset you need.

🔍

Passport inspection

Click any row to expand the full .qtrace passport: SHA-256, image metadata, validation stamp, alignment matrix, segmentation steps, and pixel classifier details including SHA-256 + Git hash.

📊

Fidelity tracking

Each classifier shows fidelity — HIGH if unchanged since training, DEGRADED if the JSON was modified post-training. Catches silent model drift before it reaches the report.
