Emperor is an interactive next generation tool for the analysis, visualization and understanding of high throughput microbial ecology datasets.
Due to its tailor-made graphical user interface, delving into a new dataset to elucidate the patterns hidden in the data, has never been easier. Emperor brings a rich set of customizations and modifications that can be integrated into any QIIME or scikit-bio compliant dataset; with lightweight data files and hardware accelerated graphics, constitutes itself as the state of the art for analyzing N-dimensional data using principal coordinates analysis.
