## Get the emission distribution parameters.

### Description

This function accesses the emission distribution parameters of the TFFM.

### Usage

      getEmissionProb(tffm)

### Arguments

`tffm` | A `TFFMFirst` object or a `TFFMDetail` object.

### Details

This function accesses the emission distribution parameters for each position of the TFFM. It returns the probability of emitting certain nucleotide based on the nucleotide on the previous site.

### Value

A matrix of `numeric` with dimensions of 16 * `ncol(tffm)`.

      tffmFirst <- readXMLTFFM(xmlFirst, type="First")
      getEmissionProb(tffmFirst)
