kemal 81a7e262b3 P5: cloud task for cohort QC validation; configurable gp3 throughput; batched contamination map
- scripts/cloud/tasks/p5.sh: P4 preset re-check, genotype (v5) with QC, validate_p5_large.py
- scripts/validate_p5_large.py: identify samples via het pattern vs 1000G VCF; sex, parent-offspring,
  Mendel, contamination/control distributions
- trial.sh: DISK_MBPS / DISK_IOPS
- qc/contamination: bounded map batches (executor.map submits eagerly)

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

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 in progress: control-probe metrics, thresholds/profiles, two-axis sample status, BAF-regression contamination, KING-robust relatedness, Mendelian errors and the locus summary are implemented and match their open-source references on the GSA demo set (docs/validation/P5.md); the cohort-scale validation and the HTML report are pending. Available commands: simurg version, simurg inspect <files…> [--json], simurg ingest, simurg normalize, simurg genotype, simurg qc controls|samples|contamination|relatedness|loci|suggest-thresholds.

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)
uv run simurg inspect data/p0/gsa_v4_pgx/idats_Demo_36/idats_Demo_36/207895980019/207895980019_R03C01_Grn.idat
