2020 BLAST NEWS¶
Tue, 17 Nov 2020¶
New Columns added to the Description Table.¶
A user driven enhancement to improve the BLAST solution.
Tue, 05 Nov 2020¶
A new version BLAST+ (2.11.0) is here.¶
This version supports a new usage reporting service and a new multi-theading feature.
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.
Tue, 13 Oct 2020¶
BLAST now supports the new RefSeq Select databases.¶
The RefSeq Select data-set consists of a representative or “Select” transcript for every protein-coding gene.
Tue, 29 Sep 2020¶
A new feature was added to Primer-BLAST.¶
We have added a new function to Primer-BLAST that helps users design primers common for a group of highly similar sequences.
Thu, 10 Sep 2020¶
New BLAST Default Parameters and Search Limits.¶
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

A new version IgBLAST (1.15.0) is here.¶
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.
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.
