Genome-wide association studies (GWAS) are an effective method for investigating the genetics of natural phenotypic variation in many different model organisms.Here we present GWA-Portal, an interactive web application that enables researchers to upload their phenotypes and easily carry out GWAS directly in the browser. We will present all the steps needed-from uploading the phenotype to interpreting the results-using a published root phenotype.
