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
