You can use resampling (sometimes called permutation test) in this case. Assuming your gene list is L, you can sample A of size 80 and B of size 45 independently from L, and see if the size of intersection is more or less than 15. By repeating this many times you get an estimate of probability of an overlap of size as odd as 15 by the ...

We will focus on the genes that have an adjusted p-value (those that have been tested) and that have unique ENTREZ gene identifiers. WebThe reference gene list method calculates the MR values between the genes in the list using the first gene in the list as the primary referenece gene. Gene lists can be separated by: tab, new line, vertical tab, space and comma. By default MutRank will find the 200 coexpressed genes using Pearson’s Correlation Coefficient (PCC) values (Fig ...

Web24 sep. 2012 · A popular alternative to the hypergeometric test for assessing the relevance of pathways is the gene set enrichment analysis (GSEA). This method considers the relative positions of pre-defined gene sets (pathways) in a rank-ordered list of differentially expressed genes, in order to determine if a pathway is relevant to the experimental study. Web13 sep. 2016 · I have a similar problem: I have a list of genes differentially expressed in cell B between "control vs Knock Out" experiment.
