2013-06-19:   Update to SRA-BLAST. more...less...

SRA-BLAST has undergone a dramatic update, both in terms of user interface and search performance.

SRA-BLAST now includes:

  • Targeted searching within one or more SRA Experiment sets (i.e., "SRX accessions"). Users may now search combined datasets of up to 2 billion individual reads.
  • An "autocomplete" feature that will allow users to specify SRX accession, SRX title, organism scientific name, or tax id to help build the search set.
  • Data obtained from Roche 454 and newer Illumina instruments (HiSeq and MiSeq) are now included in the SRA-BLAST database, owing to longer read lengths from these technologies.
These updates to SRA-BLAST make it an even more useful tool for searching through the more than 700 trillion open-access bases currently housed within the SRA.

Overview

The Sequence Read Archive (SRA) stores raw sequence data from "next-generation" sequencing technologies including 454, IonTorrent, Illumina, SOLiD, Helicos and Complete Genomics. In addition to raw sequence data, SRA now stores alignment information in the form of read placements on a reference sequence.

SRA is NIH’s primary archive of high-throughput sequencing data and is part of the international partnership of archives (INSDC) at the NCBI, the European Bioinformatics Institute and the DNA Database of Japan. Data submitted to any of the three organizations are shared among them.
