lobster-genomics

Genomics analysis for VCF and PLINK data with GWAS, QC, and variant annotation capabilities.

Installation

pip install lobster-genomics

Agents

Agent Description
genomics_expert Full genomics workflow orchestration including data loading, quality control, GWAS analysis, and variant annotation.

Services

Service Purpose
GWASService Genome-wide association study analysis with linear/logistic regression
VariantAnnotationService Variant functional annotation via Ensembl VEP integration
GenomicsQualityService Comprehensive QC including call rate, MAF, HWE, and heterozygosity

Features

  • Load VCF files (whole genome sequencing) and PLINK files (SNP arrays)
  • Comprehensive quality control with configurable thresholds
  • Call rate filtering at both sample and variant level
  • Minor allele frequency (MAF) filtering for rare variant removal
  • Hardy-Weinberg equilibrium testing for genotyping errors
  • Heterozygosity outlier detection for sample quality assessment
  • Linear and logistic regression GWAS with covariate support
  • Lambda GC calculation for population stratification assessment
  • Principal component analysis (PCA) for ancestry detection
  • Variant functional annotation via Ensembl VEP API
  • Manhattan plots and QQ plots for GWAS visualization
  • PCA scatter plots colored by phenotype or ancestry

Requirements

  • Python 3.12+
  • lobster-ai >= 1.0.0
  • cyvcf2 (VCF parsing)
  • bed-reader (PLINK file support)
  • sgkit (GWAS and PCA analysis)

Tier Requirement

This is a premium agent. Access is controlled at runtime via Lobster AI's tier system.
