+**What it does**
+
+Performs digital differential gene expression analysis between two groups (eg a treatment and control) each with biological replicates, from count data arranged in a matrix as a tabular file.
+
+**Input**
+
+A matrix consisting of non-negative integers. The matrix must have a unique header row identifiying the samples, as well as a unique set of row names 
+as  the first column. To create appropriate input files, the "Multiple BAMs to matrix" tool takes multiple bam files containing mapped RNAseq reads mapped to a reference genome, and a BED file containing (eg Refseq) contigs. A count matrix containing contigs as rows and samples as
+columns will be created and can then be used in this tool to estimate differential gene expression using methods appropriate for count data.
+
+**Output**
+
+A tabular file containing relative expression levels, statistical estimates of differential expression probability, the R script, log and sessionInfo, and some helpful diagnostic plots.
