**What it does**

This is a parser for the output files coming from "Bismark Methylation Caller" or "BSMAP Methylation Caller". The data is parsed into WIGGLE format.

Other options:
    -	define context of cytosines should be reported (CpG, CHG, CHH)
    -	define the minimum sequencing depth (coverage) of cytosines should be reported

**Output format**

You get one file for methylation and/or coverage (depending on what you choose under "Which files should be etracted?").

The output has the following columns::    

    Column  	Description
    ------  	--------------------------------------------------------
      1 	cytosine position
      2  	methylation state (in %) / coverage
		(positive value for plus strand / negative value for minus strand)
