- With the Comparative Genome Viewer you can compare two assemblies to see differences in genomic sequence and structure. Check out our new visualization tool! ow.ly/6aTK50K4S7W #NCBICGR
- NCBI Hidden Markov Models (HMM) Release 13.0 is now available! This release has 16,143 HMMs and 315 new HMMs since release 12.0. Learn more:
- We are excited to announce cleaner nucleotide (nt) and protein (nr) BLAST databases with more accurate results! We now use NCBI quality assurance tools to systematically remove misleading sequences. Learn more: ow.ly/CEk950RlpoM #NCBICGR
- RefSeq prokaryotic genomes and proteins are now annotated with Gene Ontology (GO) terms! Learn more: loom.ly/39YAUuM
- If you use NCBI Datasets, this message is for you! Please update to the latest version of the command line tool to retrieve updated taxonomic data. An old version will return an error for updated taxonomy ranks. More about taxonomic updates: ncbiinsights.ncbi.nlm.nih.gov/2025/02/27/new…
- Get rapid access to #Wuhan #coronavirus sequence data and analytics. Newly-released GenBank data available here: go.usa.gov/xdjvv
- 📣Introducing the Multiple Comparative Genome Viewer (MCGV)! While our existing Comparative Genome Viewer (CGV) allows you to compare pairs of eukaryotic assemblies, the new MCGV tool helps you analyze multiple assemblies in a single view. More: ow.ly/PnPg50UHIBp #NCBICGR
- Now available! You can get faster, more focused search results with our new BLAST core nucleotide (core_nt) database. The core_nt database will become the default in August 2024. Learn more: ow.ly/o0JP50SFxS6 #NCBICGR
- Get rapid access to #Wuhan #coronavirus sequence data from the current outbreak as it becomes available. We will continue to update the page with newly released data. go.usa.gov/xd2Mc
- Have you explored NCBI’s Multiple Comparative Genome Viewer (MCGV)? This tool helps you analyze whole genome alignments & gene annotation across multiple species. You can now zoom to a sequence to see small variants, alignment gaps, and insertions. More: bit.ly/3UuxRTn
- We are pleased to announce the release of the Database of Single Nucleotide Polymorphisms (#dbSNP) Build 157, which has approximately 1.2 billion Reference SNP (rs) records across the human genome! Learn more: ow.ly/rsSF50VjTCj
- Download release 17.0 of the NCBI protein profile Hidden Markov models (HMMs) used by the Prokaryotic Genome Annotation Pipeline (PGAP). This release contains 17,433 HMMs and 386 new HMMs since release 16.0. Learn more: ow.ly/oEQ750UtBS1
