# Feature barcode assignment: 10x TotalSeq-B public lane - Category: `Public data` - Assay type: `feature_barcode` - Evidence level: Documented example - Dataset: 10x Genomics TotalSeq-B antibody Feature Barcode R2 sample - Condition shown: Per-read fixed-window feature-barcode assignment with exact-slice baseline agreement. - Primary report: [docs/benchmarks/feature_barcode/README.md](../../benchmarks/feature_barcode/README.md) ## What This Shows - DotMatch can perform fixed-window per-read feature-barcode assignment on a public 10x-style lane. - The report keeps per-read assignment semantics separate from cell/UMI quantification. ## What It Does Not Show - This is not Cell Ranger feature-count replacement evidence. - Cell barcode, UMI aggregation, and cell-level feature quantification are outside this lane. ## Comparator And Validation Comparator semantics: The public lane uses the 10x feature reference fixed R2 pattern and a transparent exact-slice hash baseline for per-read fixed-window assignment. Validation: The public gate requires synthetic diagnostics, public DotMatch k=0 and k=1 rows, zero validation mismatches, and exact agreement between DotMatch k=0 and the exact-slice baseline. ## Report Examples - [Feature-barcode benchmark report](../../benchmarks/feature_barcode/README.md) (`markdown`) ## Raw Artifacts - [benchmarks/raw/feature_barcode.csv](../../../benchmarks/raw/feature_barcode.csv) - [examples/feature_barcode/data/metadata.json](../../../examples/feature_barcode/data/metadata.json) ## Reproduce Or Check - `make bench-feature-barcode-public` - `make feature-barcode-public-gate`
