2015-07-29New: Scheduled maintenance (9:30-11:30, 5 Aug.)

From 9:30 to 11:30 (planned), 5th, August, the DRA, BioProject and BioSample submission and search services will be unavailable due to scheduled maintenance.

2015-04-23: Attention for alphabetical sorting of BioSamples submitted from D-way

After submitting BioSamples from D-way, BioSamples are sorted in alphabetical (ASCII code) order of sample_name values and NOT in order of appearance (top to bottom in tab-delimited text file). BioSample accession numbers are issued to the alphabetically-sorted BioSamples.

Please enter sample_name values as such their "order of appearance" and "alphabetical order" to be same.

Since the sample_name is used as the identifier in database system, it cannot be changed after submission. Submitters can name sample by using the sample_title attribute. The sample_title is used as a title in public record and can be updated.

sample_names contain serial numbers

Following samples are sorted as intended.

0002_a sample
0003_b sample

Following examples are NOT sorted as intended (sorted by first letters).

5_a sample
10_b sample
10_b sample
5_a sample

DDBJ is developing the database system to preserve order of appearance (top to bottom in tab-delimited text file). If you have questions, please contact us from here.

DDBJ Sequence Read Archive (DRA) is an archive database for output data generated by next-generation sequencing machines including Roche 454 GS System®, Illumina Genome Analyzer®, Applied Biosystems SOLiD® System, and others. DRA is a member of the International Nucleotide Sequence Database Collaboration (INSDC) and archiving the data in a close collaboration with NCBI Sequence Read Archive (SRA) and EBI Sequence Read Archive (ERA). Please submit the trace data from conventional capillary sequencers to DDBJ Trace Archive.
