WebNov 17, 2024 · Differential expression analysis of genomic data types, such as RNA-sequencing experiments, use linear models to determine the size and direction of the changes in gene expression. For RNA-sequencing, there are several established software packages for this purpose accompanied with analysis pipelines that are well described. WebThe Model for data normalisation, Deseq2, for example, uses its own size factors method, where edgeR uses multiple methods (Though mostly TMM). and 2. The method of defining differential expression. Deseq2 and EdgeR use an exact test, where baySeq uses a comparison of posterior probabilities for diff and non-differentially expressed genes.
