BLAST+ 2.13.0 now available with SRA BLAST, ARM Linux executables, and database metadata

BLAST+ 2.13.0  includes several important new features including SRA BLAST programs, ARM Linux executables, and the ability to produce database metadata as well as some important improvements, and a few bug fixes.  You can download the new BLAST release from the FTP site.

New features

SRA / WGS BLAST (blastn_vdb, tblastn_vdb)

Beginning with this release, the BLAST distribution now includes the SRA BLAST programs  blastn_vdb and tblastn_vdb that can directly search SRA and WGS projects without the need to build a BLAST database. See the BLAST documentation on how to use these programs with WGS projects.

ARM Linux executables

This release also includes executables compiled under ARM Linux for the first time. Please let us know if you find any issues with ARM Linux programs.

Database metadata in JSON format

Starting with BLAST+ 2.13.0, the makeblastdb program generates an additional file with the file extension .njs for nucleotide databases or .pjs  for protein databases. These files contain BLAST database metadata in JSON format. See the BLAST database metadata section in the BLAST User Manual for an example. This file can be easily read by many tools and makes the BLAST database more compliant with FAIR principles.

See the release notes for more details on improvements and bug fixes for the release.

Important reminder about usage reporting

As we announced previously, BLAST can report limited usage information back to NCBI. This information shows us whether BLAST+ is being used by the community, and therefore is worth being maintained and developed.  It also allows us to focus our development efforts on the most used aspects of BLAST+.  Please help us improve BLAST by allowing BLAST to share information about your search. The BLAST privacy statement  provides details on the information collected, how it is used, and how to opt-out of reporting if you don’t want to participate.
