Earlier this year, NCBI announced plans to retire the Clone DB web interface. Pursuant to this retirement, starting on May 27, 2019, all web pages associated with Clone DB and CloneFinder will redirect to this blog post. Links to Clone DB from the NCBI home page will also be going away.
We have been offering the new BLAST results page (Figure 1) for you to try out since April and have been collecting your comments and feedback. Thank you all for your input on this new results display. Over 90% of your comments have been positive. We have made several changes to the page that address issues or problems that you have pointed out and are also working on adding several additional features that you have suggested in future releases.
At this time, 96% of you who have tried the new page have kept it as your default results page. We are planning to make the new page the default for everyone on August 1, 2019. We will still provide access to the old results for some time to allow people who have workflows or teaching materials to adjust to the new display.

Please view our video introduction to the new results to see highlights of the improved display. As always, we will continue to incorporate your feedback into the design and features on the new page, so please test it out and let us know what you think.
In March and April, the NCBI Eukaryotic Genome Annotation Pipeline released new annotations in RefSeq for the following organisms:
IgBLAST is a popular NCBI package for classifying and analyzing immunoglobulin (IG) and T cell receptor (TCR) variable domain sequences. We’ve released a new version (1.14.0) of IgBLAST with three new improvements / bug fixes:
IgBLAST 1.12 is available for download from the BLAST FTP area. See the the new manual on GitHub for information about setting up and running IgBLAST.
RefSeq release 94 is now available through NCBI web services, FTP and through NCBI’s Entrez programming utilities, E-utilities.
This full release incorporates genomic, transcript, and protein data available, as of May 13, 2019 and contains 200,311,267 records, including 141,839,334 proteins, 26,534,602 RNAs, and sequences from 91,873 organisms. The release is provided in several directories as a complete dataset and also as divided by logical groupings.
We are happy to announce that you can now submit your genome sequences annotated by your own local copy of the standalone Prokaryotic Genome Annotation Pipeline (PGAP) to GenBank.
How does it work? Download PGAP from GitHub, provide some basic information and the FASTA sequences for your genome sequence, and run the pipeline on your own machine, compute farm or the cloud. PGAP will produce annotation consistent with NCBI’s internal PGAP. Submit the resulting annotated genome to GenBank through the genome submission portal, and get an accession back.
As with any other submitted assembly, PGAP-annotated genomes will be screened for foreign contaminants and vector sequences at submission. Any annotated assemblies that don’t pass may need to be modified. We are developing an automated process to handle these edits!
We are also working on other improvements to stand-alone PGAP such as a module for calculating Average Nucleotide Identity (ANI) to confirm the assembly’s taxonomic assignment. Stay tuned for new developments!
Next Wednesday, May 15, 2019 at 11AM, NCBI staff will show you how to use the latest version of standalone BLAST+ (2.9.0) and the new accession-based DBv5 databases with built-in taxonomy information. You will learn how to limit searches to taxonomic groups and to retrieve sequences from the database by taxonomy without having to download an identifier list. You will also learn about additional improvements in the BLAST databases and programs that make them compatible with the new PDB identifiers and gi-less proteins from the Pathogen Detection Project.
Date and time: Wed, May 15, 2018 11:00 AM – 11:30 AM EDT
After registering, you will receive a confirmation email with information about attending the webinar. A few days after the live presentation, you can view the recording on the NCBI YouTube channel. You can learn about future webinars on the Webinars and Courses page.
We are pleased to announce the first ever Computational Medicine in the Cloud Hackathon! NCBI will help run a bioinformatics hackathon in Baltimore, Maryland hosted by the Johns Hopkins University.
GenBank release 231.0 (4/19/2019) is now available on the NCBI FTP site. This release has 5.03 terabases and 1.54 billion records.
The release has 212,775,414 traditional records containing 321,680,566,570 base pairs of sequence data. There are also 993,732,214 WGS records containing 4,421,986,382,065 base pairs of sequence data, 311,247,136 bulk-oriented TSA records containing 277,118,019,688 base pairs of sequence data, and 24,240,761 bulk-oriented TLS records containing 9,623,321,565 base pairs of sequence data.
NCBI is testing a new way to find and retrieve orthologous vertebrate genes. To find orthologs enter a gene symbol (e.g. RAG1) or a gene symbol combined with a taxonomic group (e.g. primate RAG1). Select the matching entry from the suggestions menu or you can select the orthologs option (e.g. Rag1 orthologs) to see all orthologs. Your search will return a results link to the set of orthologs provided by NCBI’s Gene resource. Click on the results link to see information for that ortholog group (Figure 1).
