 Note: You can find more information <NextLink href="/docs/04__Analyze%20Public%20Data/4_3__Algorithms%20and%20Ontologies#differential-expression">here</NextLink> about how our differential expression is calculated. In brief, we use a Welch's t-test. While we are aware that single cell data does not always meet the assumptions imposed by this test, we utilize it because it performs well at identifying the _most_ differentially expressed genes, and this is what our feature returns.
