Programmatic access to Gene data using Datasets command-line and API

In March, we announced NCBI Datasets, a new resource that lets you easily retrieve and download data from across NCBI databases. Did you know you can now fetch NCBI Gene data programmatically using the NCBI Datasets API or command-line tool?  Quickly retrieve both metadata and gene sequence data for multiple Gene records including transcripts and proteins in one shell command or API request. The API documentation is a good way to get started with programmatic access (Figure 1).

Figure 1. The Datasets API documentation showing a demonstration retrieving Gene metadata using RefSeq mRNA accessions. The API returns a readily processed JSON object.

NCBI Presents Two Online CoLabs at ASHG 2020!

NCBI Presents Two Online CoLabs at ASHG 2020!

Two up-and-coming NCBI resources will be featured in videos, surveys and live events at the American Society for Human Genetics (ASHG) 2020 Annual Meeting. Come and watch on-demand videos in the CoLab Theater. Then, let us know what you think and how you do or might use these resources by either taking an online survey or joining us for the CoLab Live! Events on Thursday, October 29, 2020.

NCBI Datasets now provides downloads of gene data for more than 30 thousand organisms

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).

Figure 1. The Data tables web download. Top panel. Enter or upload a list of gene identifiers or symbols. Bottom panel. The resulting table display allows you to browse results, download the table or the sequence data for the genes (genomic, transcripts, proteins).  Continue reading “NCBI Datasets now provides downloads of gene data for more than 30 thousand organisms”

Easily download large amounts of genomic data with NCBI Datasets

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.Datasets download process

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.

Announcing NCBI Datasets – try it out!

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.

Here’s what it looks like when you search ‘apes’:
