BLAST+ 2.12.0 now available with more efficient multithreaded searches

BLAST+ 2.12.0  programs feature better multithreaded searches and support a different threading model, threading by query, that can be more efficient in some situations.  The new release is also fully compatible the increase in the numeric range for the GI identifier, which will take effect in the nucleotide database later this year.  The list below shows details of the new features and bug fixes.  You can download the new BLAST release from the FTP site.

December 9 Webinar: Using BLAST+ in Docker and on the cloud

December 9 Webinar: Using BLAST+ in Docker and on the cloud

Join us on December 9, 2020 to learn about containerized BLAST+ in Docker that is ready to use locally and in the cloud. We are staging BLAST databases in some cloud providers making running containerized BLAST as part of a pipeline in the cloud even easier. In this webinar you will learn about the advantages of containerized BLAST and learn how to use it in some practical examples. You will also learn about Elastic BLAST, a cloud application that is useful for aligning extremely large numbers of sequences against BLAST databases.

  • Date and time: Wed, December 9, 2020 12:00 PM – 12:45 PM EST
  • Register

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.

BLAST+ 2.11.0 now available with limited usage reporting to help improve BLAST

BLAST+ 2.11.0 release is now available from our FTP site.  With this release, BLAST+ now provides usage reports to NCBI to help us improve BLAST.  This information is limited to the name of the BLAST program, some basic database metadata, a few BLAST parameters, as well the number and total size of your queries (Figure 1).

Figure 1. An example of the report sent back to NCBI from the 2.11.0 BLAST programs.

BLAST+ database improved

We’ve made some recent enhancements to the BLAST+ applications that allow you to:

  1. Limit your search by taxonomy using information built into the BLAST databases
  2. Search sequences by accession faster
  3. Use blastdbcmd to retrieve sequences by taxonomy from a BLAST database

The new version of the BLAST databases (version 5, release notes) supports the items listed above. You can access the new executables on FTP. Sample version 5 databases are also available.

Note: This is an alpha release to allow users to test and comment on new features.
