SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires dnaerys, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

It removes the friction of manually exploring 1000 Genomes Project data by turning cohort queries, variant lookups, and sample selection into repeatable, precise workflows.

Core Features & Use Cases

  • Variant discovery and counting: Count or list variants across GRCh38 regions, either cohort-wide or restricted to named samples.
  • Participant-level analysis: Identify which individuals carry matching variants, which are homozygous reference at a position, and how closely two samples are related.
  • Offline cohort metadata: Look up sample pedigrees, populations, and superpopulations from the bundled dataset without network access.
  • Use case: A researcher can resolve a gene to coordinates, find likely pathogenic variants in that interval, then narrow the results to a specific population and inspect the carriers.

Quick Start

Ask the skill to query the 1000 Genomes Project for a GRCh38 region or sample set you already resolved and specify whether you want counts, matching individuals, or the underlying variants.

FAQPage Schema
How do I query 1000 Genomes Project participant data at the individual sample level?

Query 1000 Genomes Project participant data by specifying validated GRCh38 coordinates and sample sets to retrieve matching individuals, variant counts, or underlying variants. The workflow requires zygosity controls, annotation filters, and pagination for precise cohort analysis.

Can I identify homozygous-reference calls and kinship relationships between 1000 Genomes samples?

Identify homozygous-reference calls and perform kinship checks between 1000 Genomes samples directly. The skill supports individual-level analysis to determine which samples carry matching variants and how closely two participants are related using bundled pedigree data.

How do I count variants across a GRCh38 region for a specific population in the 1000 Genomes dataset?

Count variants across GRCh38 regions by defining the genomic interval and restricting the query to named samples or specific populations. You can resolve a gene to coordinates, find variants in that interval, and narrow results to a selected population group.

Does querying 1000 Genomes population metadata require a network connection?

Querying 1000 Genomes population metadata does not require a network connection. The skill bundles sample pedigrees, populations, and superpopulations offline, allowing you to look up cohort metadata and perform reproducible analysis without external network access.

What are the limitations when performing variant discovery and cohort selection on 1000 Genomes data?

Limitations include the requirement for validated GRCh38 coordinates, strict zygosity controls, annotation filters, and pagination. Reproducible cohort analysis depends on providing precise inputs and correctly managing the bundled pedigree data to avoid inaccurate sample selection.
