    <help><![CDATA[
This tool creates differentially methylated positions (DMPs) with respect to a phenotype covariate. The phenotype may be categorical (e.g. cancer vs. normal) or continuous (e.g. blood pressure). 

The output is an interval file with the following columns:

    - chr
    - start
    - end
    - names
    - pvalue
    - qval
