\description{Various normalization methods.
}
\usage{

standarizationNormalize(nd) 
min_maxNormalize(nd)
densityNormalize(nd)
globalCountsNormalize(nd, sums)

}

\arguments{
  \item{nd}{nucleotide distribution object 
}
  \item{sums}{sum of reads in a sequencing sample 
}

Normalizations of a single coverage profile for multiple 
samples contained in the \code{NucleotideDistr} object. 
Full description will follow in a paper.
