  We present CloudSTRUCTURE, an application for running parallel analyses with
the population genetics program STRUCTURE. The HPC ready application, powered
by iPlant cyber-infrastructure, provides a fast (by parallelization) and
convenient (through a user friendly GUI) way to calculate like-lihood values
across multiple values of K (number of genetic groups) and numbers of
iterations. The results are automati-cally summarized for easier determination
of the K value that best fit the data. In addition, CloudSTRUCTURE will
reformat STRUCTURE output for use in downstream programs, such as TASSEL for
association analysis with population structure ef-fects stratified.
