All of Us Research Program Participants Fuel Both Scientific and Personal Discovery
The NIH’s All of Us Research Program is a historic effort to create an unprecedented research resource that will speed biomedical breakthroughs, transform medicine and advance health equity. To create this resource, we are enrolling at least 1 million people who reflect the diversity of the United States.
Scrubbing human sequence contamination from Sequence Read Archive (SRA) submissions
Do you work with human-derived sequence data? Do you often struggle with the need to determine if your data is free of human sequence and therefore suitable for public distribution? We encourage submitters to screen for and remove contaminating human reads from data files prior to submission to SRA. To support investigators in this effort, … Continue reading Scrubbing human sequence contamination from Sequence Read Archive (SRA) submissions
