WebTest overlap between two gene lists using Fisher's exact test. Description Given two gene lists, tests the significance of their overlap in comparison with a genomic background. The null hypothesis is that the odds ratio is no larger than 1. The alternative is that the odds ratio is larger than 1.0. Web16 mei 2024 · Hypergeometric distribution calculates the probability of getting a certain number of genes that overlap with your peaks (which is the same as sampling some balls and calculate the p-value of some balls with one color). The hypergeometric test calculates a p-value to see whether this number of overlapping genes is more than expected. herbsaint food
