The GWAS Catalog is a major repository for full summary statistics from genome-wide association studies. We encourage authors to submit their data to us, to make them accessible and reusable by the wider GWAS community. In 2023, we are introducing some improvements to the submission process to enhance the precision and reusability of the data we collect. This webinar provides a step-by-step guide to the submission process, including recent changes to the standard summary statistics format.
