TASSEL — association mapping for diverse samples.

TASSEL (Trait Analysis by aSSociation, Evolution and Linkage) is the long-standing workhorse for GWAS and linkage-disequilibrium analysis of complex traits in large, diverse samples — GLM/MLM models, the unified mixed model, and data handling for big genotype sets. Downloads, documentation, and source now live on GitHub.
