We present STRUCTURE HARVESTER (available at http://​taylor0.​biology.​ucla.​edu/​structureHarvest​er/​), a web-based program for collating results generated by the program STRUCTURE. The program provides a fast way to assess and visualize likelihood values across multiple values of K and hundreds of iterations for easier detection of the number of genetic groups that best fit the data. In addition, STRUCTURE HARVESTER will reformat data for use in downstream programs, such as CLUMPP.
