  1. 1 Data Structures | Data Elements Advancing Autism Discovery Workshop

    NDAR Data Organization Dan Hall – NDAR Manager April 22, 2013
  2. 2 Data Structures | Data Elements  Parking – visitor

    parking is available at the Neuroscience Center Building. Parking stickers are available. See Chloe in the back of the room  Dinner - held at Bertucci’s at 6 pm. Let us know if you can’t attend  Shuttles back to the airport will be available Tuesday after the workshop. Contact Chloe to confirm registration  Reimbursement – remember to save/send receipts after the workshop  Make sure you can connect to the internet and to NDAR Logistics
  3. 3 Data Structures | Data Elements • 10,000 -omic observations

    (4,500 exomes) • 1,000 ASD Images 4,000 Controls Harmonization Standards • Common Subject Identifier (NDAR GUID) • Data Dictionary Containing 400+ measures/45,000 Elements • Validation Tool Checks Data to Autism Data Definition • Federated with AGRE, IAN, ATP, PediatricMRI, and soon SFARI Access Requirements • Individual/Lab sponsored by an NIH recognized institution with a Federal Wide Assurance • A research question Query • Data from Labs – 90 projects sharing data • Data from Papers – Links publications to underlying data • Filter (e.g. phenotype, scores, omic alteration, imaging modality) • Download (requires sponsorship)
  4. 4 Data Structures | Data Elements Sharing to a Harmonized

    Data Standard
  5. 5 Data Structures | Data Elements Harmonization Matters  In

    total, there are 415 data structures defined using the Autism Data Standard containing shared data, meaning 415 database tables in NDAR, Pediatric MRI, ATP, AGRE, CPEA/STAART and SFARI)  Duplication across repositories is being fixed for AGRE/NDAR/CPEA/STAART  Have definitions and descriptions across 40,000 data elements. Now adding meanings of values  The NDAR GUID is pervasive, but for retrospective data, subjects are misaligned across modalities. This can/should be fixed!  match phenotype/imaging/omics of retrospective data for the following (Rutgers, SFARI, ATP, CPEA/STAART, AGP, AGRE, Coriell, etc.) ̶ Submissions of data using Resolve Identifiers and we’ll identify the same subjects across repositories/submissions
  6. 6 Data Structures | Data Elements Inspection of 400+ data

    structures is cumbersome: To simplify NDAR aggregates important data for query: Querying Across Data Structure
  7. 7 Data Structures | Data Elements Query and Download All

  8. 8 Data Structures | Data Elements Searchable Fields

  9. 9 Data Structures | Data Elements Login

  10. 10 Data Structures | Data Elements Package Creation

  11. 11 Data Structures | Data Elements  Launch Download Manager

    for “fast” download  2 terabytes (e.g. Pediatric MRI) into your lab will take a week if you have dedicated 45mbps speed to yourself  100 terabytes may take a year  The takeaway is… Download
  12. 12 Data Structures | Data Elements Download to your lab:

    1. First download without the files – no big deal 2. Download with files – 200GB maximum is the default, but packages up to 10 TB while not ideal, OK 3. Ship disks – Logistically challenging Compute in the cloud: 1. Create tiny database with references to omics/imaging files 2. Create instance in the cloud for computational processing Download Options
  13. 13 Data Structures | Data Elements  Enable any Data

    element to be used to see data distribution and use it for cohort selection  Federated data sources included in query/download  Omics experiment definition expanded to include EEG, EyeTracking, fMRI evoked response  Make Data from Papers simpler to use and support sharing at the cohort level  Real-time integration with computational pipelines Futures (Summer 2013)
