Accession numbers

When metadata and sequence data are successfully registered, accession numbers are assigned.

  • Experiment (prefix DRX)
  • Run (prefix DRR)
  • Analysis (prefix DRZ)
  • Submission (prefix DRA)

Regarding how to cite accession numbers, see “FAQ: Which accession numbers should be cited in publication?”.

Data release

The DRA submission is released according to the data release policy. Please see “FAQ: How are linked BioProject/BioSample/sequence data released?” regarding how linked data are released.
After data release process, data files are released at ftp, indexed by DDBJ Search, and mirrored by NCBI SRA and EBI SRA in a few days.

All data in a submission are released at the same time. If you want to release data at different time, please divide a submission.

Limited-time access to archived data files

To allow submitter to download and check archived fastq/SRA files, the files are copied to the following directories on the ftp-private.ddbj.nig.ac.jp server. To save disk space, the copied files are deleted in one month.

  • (submitter’s home)/report/dra/(DRA submission accession)/fastq/
  • (submitter’s home)/report/dra/(DRA submission accession)/sra/

Example: /report/dra/DRA000001/fastq/DRR000001.fastq.bz2
