# BLAST+ 2.13.0


# BLAST - Basic Local Alignment Search Tool

BLAST finds regions of similarity between biological sequences. The program
compares nucleotide or protein sequences to sequence databases and calculates
the statistical significance. 

## Update notes

BLAST+ 2.13.0 is here!

Thu, 17 Mar 2022 12:00:00 EST

Starting with this release, we are including the blastn_vdb and tblastn_vdb
executables in the BLAST+ distribution. These executables can directly search
SRA and WGS projects without the need to build a BLAST database. See
https://ftp.ncbi.nlm.nih.gov/blast/WGS_TOOLS/README_BLASTWGS.txt for
information on using these executables with WGS projects.

We have also produced ARM LINUX executables and placed them on the FTP site
(ncbi-blast-2.13.0+-x64-arm-linux.tar.gz). These executables have passed our
normal QA, but this is our first release for this architecture. Please let us
know if you find any issues.

Usage reporting - Help improve BLAST by sharing limited information about your
search. Details on the information collected, how it is used, how to opt-out,
and our privacy statement is found here:

## rpsbproc is included

`rpsbproc` allows for filtering of `rpsblast` searches - use the databases in
`/nfs1/CGRB/databases/NCBI/cdd/latest` for this purpose.

Location and version:

```console
$ which blastn
/local/cluster/ncbi-blast+/bin/blastn
$ blastn -version
blastn: 2.13.0+
 Package: blast 2.13.0, build May 13 2022 11:32:40
```
