Sequence Read Archive (SRA)

Please login to create a new submission or to see your existing submissions.

The SRA accepts genetic data and the associated quality scores produced by next generation sequencing technologies. Please refer to the File Format Guide.

  • Files can be compressed using gzip or bzip2, and may be submitted in a tar archive but archiving and/or compressing your files is not required. Do not use zip!
  • All file names must be unique.
  • Each file must be listed in the SRA metadata table. If you are uploading a tar archive, list each file name, not the archive name.
  • Use the preload option if you are uploading files over 10 GB or more than files. All files for a submission must be uploaded into a single folder.

Before submitting, read the SRA Submission Wizard Help.

Contact sra@ncbi.nlm.nih.gov with any question or concern about your data or submission.
