# superdelta2 Superdelta procedure for multiple group differential expression analysis This is the first working version of superdelta2() that collects all scripts for relevant functions. The pipeline will work thoroughly, including the following components: 1. A main function working on differential gene expression analysis procedure that can be implemented for RNA-seq data and multiple group comparisons. 2. Two general functions of simulating RNA-Seq count data based on the Negative Binomial Poisson (NBP) model. 3. A handy function for obtaining substrings of character strings. 4. Other necessary functions to support the main function but not necessarily exported to users. This project aims at building a comprehensive analysis pipeline to identify differentially expressed (DE) genes of cancer patients, or other diseases or clinical subgroups of interest. The underlying biological mechanism of DE genes will also be carefully investigated on both gene level and pathway level. The whole procedure will practically shed light to the differential expression analysis of RNA-Seq data.
