**What it does**

Inference of differential exon usage in RNA-Seq.


**Inputs**

DEXSeq_ takes count tables generated from the dexseq_count as input. Count tables must be generated for each sample individually.
DEXSeq_ is capable of handling multiple factors that effect your experiment. The first factor you input is considered as the primary
factor that affects gene expressions. Primary factor should always be named as 'condition'. You also input several secondary factors that might
influence your experiment. But the final output will be changes in genes due to primary factor in presence of secondary factors. Each factor has two levels/states.
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    Factor level 1 Factor level 2
--------- -------------- ---------------
condition Knockdown      Wildtype
--------- -------------- ---------------
treatment Treated        Untreated
--------- -------------- ---------------
timePoint Day4           Day1
--------- -------------- ---------------
SeqType   SingleEnd      PairedEnd
--------- -------------- ---------------
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 'condition' given in above table, DEXSeq computes fold changes of 'Knockdown' samples against 'Wildtype', i.e. the values correspond to up or down regulations of genes in Knockdown samples.

**Output**

DEXSeq_ generates a tabular file containing the different columns and an optional html report.

====== ==========================================================
Column Description
------ ----------------------------------------------------------
     1 Gene and exon Identifiers
     2 group/gene identifier
     3 feature/exon identifier
     4 mean of the counts across samples in each feature/exon
     5 exon dispersion estimate
     6 LRT statistic
     7 LRT p-value
     8 BH adjusted p-values
     9 exon usage coefficient factorLevel 2
    10 exon usage coefficient factorLevel 1
    11 relative exon usage fold changes
    12 GRanges object of the coordinates of the exon/feature
    13 matrix of integer counts, of each column containing a sample
    14 list of transcripts overlapping with the exon
