NCBI introduces Datasets, a new resource that lets you easily gather data from across NCBI databases. Our first release allows you to find and download genomic sequence and annotation data for all eukaryotic organisms through our user-friendly web interface.
Our web interface also provides an interactive taxonomy tree that lets you browse for your favorite organism. We are currently testing the web interface in the NCBI labs environment. To try it out, enter a taxonomic name or assembly accession and click on the ‘Get Data’ button in the search results panel.
