Eurogenes K7 AMI

Eurogenes K7 AMI — Ancient-era admixture calculator for Europe

This calculator estimates ancestry proportions using a compact, archaeogenetically informed 7-component model optimized for European samples in the Ancient era. It compares a tested genotype against seven reference clusters: Sub-Saharan, Oceanian, Amerindian, Euro_HG, Siberian, Southeast_Asian, and Near_Eastern. The result describes how much of an individual's genome best matches each ancestral cluster.

Who it’s for:

• Researchers, students, and enthusiasts working with ancient European specimens or modern individuals seeking an ancient-aware breakdown.
• Anyone interested in broad continental and prehistoric migration signatures rather than fine-scale modern population structure.

What you can learn:

• Proportional affinities to European hunter-gatherers (Euro_HG) and Near Eastern farming groups (Near_Eastern).
• Signals of northern/eastern influx (Siberian) associated with steppe or Siberian-related ancestry.
• Presence of distal or unexpected components (Sub-Saharan, Oceanian, Amerindian, Southeast Asian) that indicate deep or recent admixture, contamination, or model artifacts.

Context and scientific grounding:

• K7 is a compact admixture framework: each component is a simplified cluster representing broad ancestral sources rather than named historical populations.
• Euro_HG reflects pre-agricultural hunter-gatherer ancestry in Europe; Near_Eastern captures agriculturalist-derived input; Siberian and others capture Eurasian steppe or far-eastern contributions and non-Eurasian affinities.

Why this calculator is valuable:

• Fast, interpretable overview useful for hypothesis generation, sample triage, and public-facing summaries.
• Especially helpful for ancient DNA projects where reduced-component models minimize overfitting and clarify major migratory events.

Limitations & best practices:

• Results depend on chosen reference panels; components are heuristic and s
