NCBI Datasets now offers Gene tables: customizable tables of the genes you specify, with key gene information, and the ability to easily download a dataset of genomic, transcript and protein sequences.
Drag and drop a list of Gene IDs or gene symbols, and the data table shows your genes with up to 15 columns of metadata, including genomic coordinates, RefSeq transcript and protein accessions, Ensembl IDs and UniProt accessions, and other gene information. You can browse and select items in your table on the web, or download everything to your computer for later analysis (Figure 1).
Do you need to download a lot of genomic data? Maybe you need all primate reference genomes or maybe you need just a few really big genomes? Prior to the advent of NCBI Datasets, downloading such a large amount of data could be a frustrating and time consuming experience involving failed downloads and writing custom scripts.
NCBI Datasets makes large genome downloads simpler, faster, and more reliable. You don’t have to write a script. You can be sure you get all the data requested. And sharing the data is easier than ever. Figure 1 shows an example data download process using Datasets.
Figure 1. Downloading and processing genomic data using NCBI Datasets. The example shows downloading the set of RefSeq primate assemblies through the Datasets web interface. Since the downloaded files would exceed 15GB, the file comes as a “dehydrated bag” — a small, easily downloaded, zipped file with metadata and links to download the data. You can “rehydrate” the unzipped dehydrated files — fill them with the corresponding data — using the datasets command-line tool.
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.
