NCBI staff will be presenting virtual posters at the Cold Spring Harbor Laboratory Biology of Genomes Meeting, May 11 -14, 2021. The posters will cover the following topics: 1) a cloud-ready suite of tools (PGAP, RAPT , and SKESA) for assembling and annotating prokaryotic genomes, 2) Datasets — a new set of services for downloading genome assemblies and annotations, and 3) updates on NCBI RefSeq eukaryotic genome annotation, and the Genome Data Viewer (GDV). Read more below for the full abstracts.
Looking for genomes for the B.1.1.7 SARS-CoV-2 variant? NCBI now supports searches for SARS-CoV-2 variant names such as B.1.1.7, B.1.351, or P.1. For example, search for B.1.1.7 (Figure 1) and you’ll see a virus classification box with an option to download a SARS-CoV-2 data package. SARS-CoV-2 data packages include genome and protein sequences and a detailed data report for all SARS-CoV-2 genomes classified as that variant. SARS-CoV-2 genome lineages are classified by pangolin, using the pangoLEARN algorithm.

NCBI Datasets, the new set of services for downloading genome assembly and annotation data (previous Datasets posts), has redesigned and reorganized web pages to make it easier to find and access the services and documentation you need.
You can now get gene ortholog data using the NCBI Datasetscommand-line tool using a gene ID, gene symbol, or RefSeq nucleotide or protein accession. Data are available for vertebrates and insects. The vertebrate orthologs includes a specialized set for fish. (See our recent post for more information on the orthologs for fish and insects.)
You can retrieve metadata for gene orthologs in JSON Format, or you can download a compressed (zip) archive containing both metadata and sequences (Figure 1).

NCBI RefSeq has finished its initial annotation of the new rat reference assembly, mRatBN7.2, recently released by the Darwin Tree of Life Project at the Wellcome Sanger Institute. This is the first coordinate-changing update to the rat reference since the 2014 release of Rnor_6.0 from the Rat Genome Sequencing Consortium and brings the rat assembly into the modern age with a nearly 300x increase in contig N50 and 9x increase in scaffold N50 lengths. It’s a major improvement!
It’s time we do another roundup of what’s been happening on YouTube!
First up, the NCBI YouTube channel has merged with the NLM YouTube channel. You’ll now be able to find diverse content all on one channel, from tips on using resources to fascinating moments in the history of medicine and more!
You can now retrieve genome data using the NCBI Datasetscommand-line tool and API by simply providing a BioProject accession. You can go directly from a BioProject accession to genome data even when the BioProject accession is the parent of multiple BioProjects (Figure 1).
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).

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.
