Database Integration to Improve Accessibility to High-Throughput Seq Data
TAZRO OHTA @inutano

What do you imagine with a term “Database”?
None
None
None
Knowledge Scientific data Experimental data
Knowledge base Database Raw Data repository
Knowledge base Database Raw Data repository
What kind of data? Next-generation is already out there…
We all need Raw data repo for NGS
We’ve already seen WHY WE NEED
None
Reproducibility is what makes science fair.
2 things required for data repository is…
1: Reliability Data should be archived correctly, with explicit metadata
2: Accessibility Data should be able to be accessed by anyone, without special trick
1: Reliability needs curation Data should be archived correctly, with
explicit metadata 2: Accessibility needs good interface Data should be able to be accessed by anyone, without special trick

explicit metadata 2: Accessibility needs good interface Data should be able to be accessed by anyone, without special trick
1: Reliability needs curation Data should be archived correctly, with
explicit metadata 2: Accessibility needs good interface Data should be able to be accessed by anyone, without special trick
Current Web-interface for DRA http://trace.ddbj.nig.ac.jp/DRASearch
Good: Simple, Fast, and no bugs (!) Challenge: Lack of
metadata caused “NOT FOUND”
PROBLEM:
???
DRASearch can NOT find Data without metadata …but they definitely
exist in the repo.
Too many to ask submitters; then we implemented a system
to make metadata rich enough
2 sources into DRA DDBJ Read Archive
Publications can have details of seq process, Seq Read Quality
can be a source of data quality. DDBJ Read Archive PubMed PMC Extracted Read Quality
And then: integration enables to implement Efficient Data Search
Available via DBCLS SRA http://sra.dbcls.jp/

Power of Integration: Metadata Search http://sra.dbcls.jp/search

83% seq reads satisfied average quality over 30 0.03% of
seq reads fall into over 50% N content
1: Reliability from paper/data qual more description brings more proof.
2: Accessibility from text-search Search included publication brings flexibility.
2.20% of submitted projects has at least one publication 4429
/ 201558 PROBLEM:

What is Next-step to carry on?
1: Beyond Raw Data Archive is going to handle alignment
data. 2: Analysis Reproducibility Public repo for analysis pipeline is required.

Database is for Biologists not for developers.
