TASSEL -Trait Analysis by aSSociation, Evolution and Linkage. Linkage disequilibrium evaluation made easy. TASSEL help you evaluate traits associations, evolutionary patterns, and linkage disequilibrium.

One of the design elements driving TASSEL development has been the need to analyze ever larger sets of data. TASSEL was designed for a wide range of users, including those not expert in statistics or computer science.

The command-line version of TASSEL, called the Pipeline, provides users the capability to software tasks using a script instead of the graphic user interface (GUI). This feature allows researchers to define tasks using a few lines of code and provides the capability to use TASSEL as part of an analysis pipeline or to perform simulation studies.

Due to the increasing availability of open data sources, TASSEL utilizes a data browser from the Genomic Diversity and Phenotype Connection (GDPC) project to provide an interface to relational databases. As a result, TASSEL users can access any data source that provides a GDPC service. Using this middleware, which provides a common graphical interface, TASSEL users can avoid writing SQL queries to access data. Currently, GDPC provides connections to Panzea, Gramene, Germinate, and GRIN.

TASSEL is written in Java, thereby enabling its use with virtually any operating system. It can be installed using Java Web Start technology by simply clicking on a link at www.maizegenetics.net/tassel.

A standalone version of TASSEL can also be downloaded to use in pipeline mode or in any situation where the user wishes to start the program from a command line.

Execute: On Windows, see run_pipeline.bat for an example how to execute the pipeline.
