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)
docs/validation/— per-phase validation reports ·docs/known_unknowns.md— findings log ·docs/research/— background
Status
v1.0.0 (2026-09-28) — see CHANGELOG.md. IDAT → normalization → GenCall-equivalent genotype calling → GTC v5 →
sample/control QC with an HTML report → plus-strand VCF/BCF → PLINK 1/2, bedGraph, final report; plus a
differential-testing harness. Validation (docs/validation/):
| Check | Result |
|---|---|
2141 vendor GTCs, 1000 Genomes Omni2.5 (--preset autocall-1.6.2) |
normalization bit-identical; GTCs byte-identical in 2138/2141 |
| GSA demo vs gtc2vcf, GTCtoVCF, plink2 | zero unexplained differences |
| 1000 Genomes pedigrees (Omni2.5) | 717/717 parent–offspring pairs; Mendel error median 0.031 % |
| 360 GSA arrays (GSE165845) vs NYGC 30x WGS / GIAB HG001 | concordance 0.9934 / 0.9985; replicates 0.9966 |

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)
bash scripts/fetch_data.sh p6 # GRCh38 FASTA (~0.9 GB download, 3.1 GB unpacked)
bash scripts/make_oracle_vcf.sh # gtc2vcf oracle VCF for the P6 tests
uv run pytest tests/oracle # real-data acceptance tests (add -m "not slow" to skip the long ones)
uv run simurg inspect data/p0/gsa_v4_pgx/idats_Demo_36/idats_Demo_36/207895980019/207895980019_R03C01_Grn.idat
