An R package for Differential Expression Analysis. Given count data from two experimental conditions, denoiSeq helps one determine which transcripts are differentially expressed across the two conditions using Bayesian inference of the parameters of a bottom-up model for PCR amplification developed in "Chromatin conformation governs T cell receptor J beta gene segment usage", by Ndifon et al.

To use the package, one needs to create a readsData object and invoke the denoiseq function on it. The results are obtained from the return value of denoiseq using the results function which then computes the test statistic used in differential analysis.

RD <- new("readsData", counts = ERCC)  #creating the readsData object

steps <- 3000  #steps for MCMC

BI <- denoiseq(RD, steps)  #invoking denoiseq on the readsData object

rez <- results(BI,steps)  #computing the test statistic

This package can be istalled from CRAN using install.packages("denoiSeq") or from github using devtools::install_github("buriom/denoiSeq").
