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.
We’ve uploaded recordings from two recent NCBI Minute webinars on the NCBI YouTube channel.
The first, “Using the SRA RunSelector to Find NGS Datasets”, shows you how to filter the SRA database using metadata details from submitted 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.
dbGaP (the NIH database of Genotypes and Phenotypes) is celebrating its 10th Anniversary this year! We are proud to support over 850 studies and 1.6 million samples.
We invite you to join us at the dbGaP 10th Anniversary Symposium to be held on June 9, 2017; 1:30-3:00 PM Wilson Hall, Building-1 on the NIH Bethesda campus. For information on Campus access and security, NIH Visitor Center, Parking, and directions to NIH, see the NIH Visitor Information page.
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.
