Upload Data and Validate Metadata with the DCA

You are now ready to upload your data and metadata. Once data is uploaded to Synapse, data contributors to the ELITE Portal will use the Data Curator App (DCA) to annotate, validate, and submit your metadata. The DCA is a web-based metadata upload application developed and managed by Sage Bionetworks.


Step 4: Upload Data

Navigate here for detailed instructions on how to upload data to Synapse. We recommend:

  • Using the Python client or command line client for faster upload speeds.

  • Authenticating with a personal access token, rather than password, to prevent timeout during a data upload.

As part of your data submission, we also request you upload your data dictionary as well.

If your data already resides in Amazon Web Services (AWS), please contact the EL DMCC via your Service Desk ticket to discuss options for possible data transfer between AWS buckets.


Step 5: Upload, Validate, and Submit your Metadata

Navigate here for detailed instructions on how to upload, validate, and submit metadata in the DCA. At a high level, the steps you will complete in the DCA are to:

  • Download the metadata template(s) matching your data submission. At minimum, this will include the:

    • Individual metadata file

    • Biospecimen metadata file

    • Assay metadata file for each type of assay data (ex. one for RNAseq, one for ChIPseq)

  • Fill in the required values for the metadata template(s) and any optional values. The ELITE Metadata Dictionary is available here for your reference.

  • Upload the completed metadata template(s) back to DCA to Validate Filled Metadata

  • Resolve errors in validation

  • Submit your metadata once no errors are found
