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).
Phase P6 (outputs) is complete: simurg gtc-to-vcf (plus-strand harmonisation with audit, merged multi-probe
sites, per-sample VCF.gz + tabix or a cohort BCF + CSI) and simurg export plink|bedgraph|finalreport|locus-summary.
On the GSA demo, genotypes match gtc2vcf and GTCtoVCF with zero unexplained differences and PLINK files match plink2
(docs/validation/P6.md).
Available commands: simurg version, simurg inspect <files…> [--json], simurg ingest, simurg normalize, simurg genotype,
simurg qc controls|samples|contamination|relatedness|loci|report|suggest-thresholds, simurg gtc-to-vcf,
simurg export plink|bedgraph|finalreport|locus-summary.
