2020 BLAST NEWS¶
New Columns added to the Description Table.¶
Tue, 17 Nov 2020¶
A user driven enhancement to improve the BLAST solution.
A new version BLAST+ (2.11.0) is here.¶
Tue, 05 Nov 2020¶
This version supports a new usage reporting service and a new multi-theading feature.
Bug fixes¶
Fix slowdown in TBLASTN searches run without composition-based statistics on long database sequences.
Remove necessity of a network connection for blast_formatter. This also speeds up blast_formatter if the database can be found locally.
A core dump for RPSBLAST and RPSTBLASTN has been fixed.
Makeblastdb for windows has been fixed to not require as much virtual memory and to not produce overly large LMDB files.
BLAST now supports the new RefSeq Select databases.¶
Tue, 13 Oct 2020¶
The RefSeq Select data-set consists of a representative or “Select” transcript for every protein-coding gene.
A new feature was added to Primer-BLAST.¶
Tue, 29 Sep 2020¶
We have added a new function to Primer-BLAST that helps users design primers common for a group of highly similar sequences.
New BLAST Default Parameters and Search Limits.¶
Thu, 10 Sep 2020¶
To provide a more useful BLAST output, maximize performance, and to make search time more consistent, webBLAST is updating some of the default parameters and search limits.
Expect Value default will be 0.05
Max target sequences limit will be no more than 5,000
Max query sequence size for BLASTn, blastx and tblastx and will be 1,000,000
Max query sequence size for BLASTp and tblastn will be 100,000
Max query/subject sequence size for blast2Sequences mode will be 10,000,000

BLAST+ 2.10.1 is released – Fix for TBLASTN Multi-Threading issue¶
Thu, 18 June 2020¶
This version supports pulling databases from our FTP site as well from cloud providers or our BLAST+Docker solution.
A new version IgBLAST (1.15.0) is here.¶
Wed, 22 Jan 2020¶
We’ve released a new version of IgBLAST with four new improvements. IgBLAST is a popular NCBI package for classifying and analyzing immunoglobulin (IG) and T cell receptor (TCR) variable domain sequences.
Improvements are:
Support for the new FWR4 annotation feature in the AIRR format, both in standard format and in the AIRR alignment format.
The previous “-penalty” parameter was renamed as -V_penalty to be consistent with other IgBLAST penalty options.
Restored constant internal BLAST search parameters for domain annotation (i.e., FWR/CDR) such that this process is not influenced by user parameters.
Corrected FWR/CDR annotations for certain mouse VK and rat VH germline genes.
IgBLAST 1.15 is available for downloadhttps://ftp.ncbi.nih.gov/blast/executables/igblast/release/LATEST/ from the BLAST FTP area. See the the new <manual on GitHub for information about setting up and running IgBLAST.
