# rnaseqde

## Syntax

## Description

uses the RNA-seq count data in `diffTable`

= rnaseqde(`countTable`

,`conditionVariables1`

,`conditionVariables2`

)`countTable`

and performs differential
expression analysis between the conditions (or samples) in
`conditionVariables1`

and `conditionVariables2`

. The
rows of `countTable`

represent genes (or features), and the columns
represent the conditions. The function first divides each condition by a library size factor
to normalize the count prior to performing the hypothesis test. This size factor is equal to
the median ratio of each feature over the geometric mean of the feature in all conditions.
The function uses an exact test to determine the differences between two groups of counts
that are each assumed to follow a negative binomial distribution [1].

specifies additional options using one or more name-value arguments.`diffTable`

= rnaseqde(___,`Name=Value`

)
