Data Submission

The GDC Data Submission Portal checks XML, JSON, and TSV metadata files for validity at the time they are submitted. If your files fail to validate, please check the error report and review the GDC Data Dictionary for troubleshooting these errors.

Information on the data submission processes and tools are available on the GDC Data Submission Processes and Tools page. Detailed instructions for submitting data into the GDC are provided in the GDC Data Submission Portal User's Guide.  Per GDC Policy, organizations interested in submitting data into the GDC must first apply for data submitter access through the NIH database of Genotypes and Phenotypes (dbGaP).
