# Barcode failure fixture: wrong offset and invalid windows - Category: `Report zoo` - Assay type: `inline_barcode` - Evidence level: Small fixture - Dataset: Committed barcode failure-mode FASTQ fixture - Condition shown: Deliberately constructed reads show wrong offset, invalid window, reverse-complement candidate, and low-complexity failure modes. - Primary report: [examples/barcode_autopsy/failure_modes/README.md](../../../examples/barcode_autopsy/failure_modes/README.md) ## What This Shows - DotMatch documents what wrong fixed-window coordinates and invalid extraction windows look like. - The fixture gives developers and users concrete examples of failure classifications. ## What It Does Not Show - This fixture is synthetic and should not be used for performance claims. - Reverse-complement findings are advisory; users must normalize assay inputs themselves. ## Comparator And Validation Comparator semantics: The fixture is a deterministic diagnostic fixture for barcode failure classifications, not a public dataset comparator. Validation: The barcode failure fixture checker requires the expected failure-mode table and matching fixture files. ## Report Examples - [Failure-mode README](../../../examples/barcode_autopsy/failure_modes/README.md) (`markdown`) - [Expected findings](../../../examples/barcode_autopsy/failure_modes/expected_findings.tsv) (`tsv`) ## Raw Artifacts - [examples/barcode_autopsy/failure_modes/expected_findings.tsv](../../../examples/barcode_autopsy/failure_modes/expected_findings.tsv) - [examples/barcode_autopsy/failure_modes/barcodes.tsv](../../../examples/barcode_autopsy/failure_modes/barcodes.tsv) - [examples/barcode_autopsy/failure_modes/reads.fastq](../../../examples/barcode_autopsy/failure_modes/reads.fastq) ## Reproduce Or Check - `make barcode-validation-ready`
