NCBI SRA Import is a utility for importing accessions from the NCBI read archives using the fast Aspera network protocol. Files imported this way, rather than via the FTP interface, will appear in the iPlant Data Store anywhere from 5-25x more quickly.

Quick Start

  • To use NCBI SRA Import, navigate to the SRA accession you wish to import. Right click on the sra or sra-lite link and copy the FTP URL to your clipboard. Paste this value into the FTP URL field in the NCBI SRA import tool. The import process will be launched as a job. This is different than the process for importing from URLs or from the desktop, which is done right in the Data window in the Discovery Environment.
  • Resources:
