SimurgArray
Personal research toolkit for Illumina Infinium genotyping BeadChip data (IDAT → normalization → genotype calling → BAF/LRR → QC → VCF/PLINK; later CN/LOH, PGx, cluster training).
- SIMURGARRAY_MASTER_PLAN.md — architecture, algorithms, roadmap
- SIMURGARRAY_FUNCTIONAL_SPEC.md — 416 itemised requirements (CLI, inputs, outputs, QC, CN, PGx, methylation, edge cases)

Status
Phases P0 (setup), P1 (file parsers), P2 (canonical model, raw X/Y), P3 (normalization) and P4 (genotype
calling, GTC output) are complete — see docs/validation/. Each is validated on 2141 vendor GTCs of the 1000 Genomes Omni2.5 set
(normalization bit-identical; genotypes/scores identical in 2138/2141 samples).
Phase P5 (QC) is complete: control-probe metrics, thresholds/profiles, two-axis status, BAF-regression contamination,
KING-robust relatedness, Mendelian errors, locus summary and a self-contained HTML report (simurg qc report). On 2141
1000 Genomes samples all 717 pedigree parent–offspring pairs are recovered and trio Mendelian error rates are ~0.03 %
(docs/validation/P5.md).
Available commands: simurg version, simurg inspect <files…> [--json], simurg ingest, simurg normalize, simurg genotype,

Quick start
uv venv && uv pip install -e ".[dev]"
uv run pytest tests/unit # no downloads needed
bash scripts/bootstrap_refs.sh # reference open-source repos → refs/ (oracles)
bash scripts/fetch_data.sh p0 # ~1.4 GB of public test data → data/
bash scripts/make_oracle_gtcs.sh # builds gtc2vcf, writes oracle GTCs
bash scripts/make_oracle_qc.sh # locus-summary oracle (BeadArrayFiles, separate venv)
uv run pytest tests/oracle # real-data acceptance tests (add -m "not slow" to skip the long ones)
