+
+**What it does**
+
+Estimate Distance between samples (MDS) and Biological Coefficient Variation (BCV) in count data from high-throughput sequencing assays and test for differential expression using edgeR_.
+
+**Inputs**
+
+edger-repenrich takes count tables generated by repenrich as input. Count tables must be generated for each sample individually. Here, edgeR_ is handling a single factor (genotype, age, treatment, etc) that effect your experiment. This factor has two levels/states (for instance, "wild-type" and "mutant".
+You need to select appropriate count table from your history for each factor level.
+
+The following table gives some examples of factors and their levels:
+
+========= ============== ===============
+Factor    Factorlevel1   Factorlevel2
+--------- -------------- ---------------
+Treatment Treated        Untreated
+--------- -------------- ---------------
+Genotype  Knockdown      Wildtype
+--------- -------------- ---------------
+TimePoint Day4           Day1
+--------- -------------- ---------------
+Gender    Female         Male
+========= ============== ===============
+
+*Note*: Output log2 fold changes are based on primary factor level 1 vs. factor level2. Here the order of factor levels is important. For example, for the factor 'Treatment' given in above table, DESeq2 computes fold changes of 'Treated' samples against 'Untreated', i.e. the values correspond to up or down regulations of genes in Treated samples.
+
+**Output**
+
+edgeR_ generates a tabular file containing the different columns and results visualized in a PDF:
+
+====== =============================================================================
+Column Description
+------ -----------------------------------------------------------------------------
+     1 Tag (transposon element ID)
+     2 the logarithm (to basis 2) of the fold change (See the note in inputs section)
+     3 p value adjusted for multiple testing with the Benjamini-Hochberg procedure
+       which controls false discovery rate (FDR)
+     4 Class the transposon belongs to
+     5 Type the transposon belongs to
+====== =============================================================================
