\title{Creation of a ExpressionSet object}
\description{
This function creates a ExpressionSet object.
}
\usage{
makeEset(mageOM, genes, directory = ".", QTD = "none", arrayID = "none", DED = "none",  derivQT = "none")
}

\arguments{
  \item{mageOM}{Reference to MAGE Object Model}
  \item{directory}{Directory which contains the MAGEML files that need to be imported}
  \item{genes}{the Gnames marrayInfo object e.g. created by getGnames}
  \item{QTD}{the Quantitation Type Dimension}
  \item{arrayID}{Array identifier}	
  \item{DED}{the Design Element Dimension}
  \item{derivQT}{the name of the QuantitationType you want to import}
