Project Statistics
High-level metrics for the Princeton connectomics annotation projects. All figures are aggregate project data.
Last updated: January 2026
Note: These statistics reflect aggregate project progress. Individual performance data is not tracked or displayed.
Summary Metrics
Dataset count from published connectomics projects.
Validation via CAVE API supervoxel tracking.
Count of current (non-deprecated) SOPs.
ID Validation Results
Root ID validation against CAVE database ensures annotation references remain current as the segmentation evolves.
| Metric | Count | Percentage |
|---|---|---|
| Total IDs Validated | 12,321 | 100% |
| Current (No change needed) | 11,473 | 93.1% |
| Updated (ID changed) | 848 | 6.9% |
Methodology
IDs validated using supervoxel-based tracking through CAVE API. Updated IDs reflect segmentation changes (splits/merges) since original annotation. See ID Validation Workflow Guide.
Dataset Overview
