Magic-BLAST 1.3.0 released with new features and improvements


The newest version of Magic-BLAST (v. 1.3.0) offers improved sensitivity and faster run-times as well as a number of other new features and improvements. These include the ability to set the alignment cut-off score as a function of read length, a maximum edit distance option and optional local cacheing for SRA files. For more information on these and other improvements, see the release notes. You can download the new executables from the NCBI FTP site.

Magic-BLAST is a tool for mapping large next-generation RNA or DNA sequencing runs against a whole genome or transcriptome. Read more here.

August 23 NCBI Minute: Using the Run Selector to Find Relevant Next-Generation Sequencing (NGS) Datasets


Do you have trouble searching the NCBI webpage for relevant datasets? Wish you could filter the search results more precisely? You can with SRA Run Selector.

In this NCBI Minute, you’ll learn how to filter the SRA database using the metadata details captured for each submitted dataset. This is easily done in a spreadsheet format that displays all recorded metadata for each SRA Run. The user-friendly interface allows you to selectively filter datasets down to the most relevant data for your research question and then export it in a spreadsheet.

Date and time: Wednesday, August 23, 2017 12:00 PM – 12:30 PM EDT

After registering, you will receive a confirmation email with information about attending the webinar. After the live presentation, the webinar will be uploaded to the NCBI YouTube channel. You can learn about future webinars on the Webinars and Courses page.

Introducing Magic-BLAST


Magic-BLAST is a new tool for mapping large sets of next-generation RNA or DNA sequencing runs against a whole genome or transcriptome. Magic-BLAST executables for LINUX, MacOSX, and Windows as well as the source files are available on the FTP site.

Each alignment optimizes a composite score, taking into account simultaneously the two reads of a pair, and in case of RNA-Seq, locating the candidate introns and adding up the score of all exons. Sequencing reads can be provided as NCBI SRA accessions, FASTA or SRA files.

Magic-BLAST implements ideas developed in the NCBI Magic pipeline using the NCBI BLAST libraries. Magic-BLAST is under active development, and we expect the next few releases to occur on a monthly basis. Read more about Magic BLAST on the FTP site.
