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 recently updated the version 5 BLAST protein databases, (dbV5), on our FTP site to be completely accession-based. As we described in a previous post, this means they now contain the gi-less proteins from the NCBI Pathogen Project and other high-throughput projects. The v5 databases are also compatible with proteins from PDB structures with multi-character chain identifiers and will include these as they become available in our other protein systems. Only the latest version of BLAST+ (2.9.0, download) will work with the updated v5 databases and allow you to access all of the most recent protein data. At the end of September 2019, we will stop updating the version 4 BLAST databases and offer the v5 databases as the default for download.
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.
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:
- Adaptive Immune Receptor Repertoire (AIRR) format is more consistent with AIRR specs including changing undefined type (NON, N/A) to empty string, not appending “reversed” to sequence identifier when the query is in reversed orientation, and using standard locus names such as IGH, TRB instead of traditional VH, VB etc.
- The logic for showing CDR3 end of TCR sequences is improved.
- The sequence identifier is restored in the case of no results in AIRR rearrangement format.
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.
