TASSEL – Trait Analysis by aSSociation, Evolution and Linkage

TASSEL is a software package used to evaluate traits associations, evolutionary

patterns, and linkage disequilibrium. Strengths of this software include:

​

1. The opportunity for a number of new and powerful statistical approaches to association mapping such as a General Linear Model (GLM) and Mixed Linear Model (MLM). MLM is an implementation of the technique which our recently published Nature Genetics paper – Unified Mixed-Model Method for Association Mapping – which reduces Type I error in association mapping with complex pedigrees, families, founding effects and population structure.

​

2. An ability to handle a wide range of indels (insertion & deletions). Most software ignore this type of polymorphism; however, in some species (like maize), this is the most common type of polymorphism.
