\title{Microarray signal channel description}
\description{With this object it is possible to describe the signal channels of a microarray experiment. This object establishes the linkage between the sample that was hybridized onto a specific signal channel of a microarray (signal channels correspond to the columns of the \code{exprs} slot of a \code{MadbSet} (or \code{ExpressionSet})).
\\
For further informations and examples refer to the package vignette (which can be opened using the \code{\link{openMadbVignette}}).

\section{Slots}{
  \describe{
    \item{\code{hyb.date}:}{The date when the sample was hybridized onto the  array.}
    \item{\code{label.date}:}{The date when the sample was labeled.}
    \item{\code{label.incorporation}:}{The method that was used to label the RNA.}
    \item{\code{color}:}{A description of the color that was used.}
    \item{\code{description}:}{A description.}
    \item{\code{array.index}:}{The index of the corresponding array in the \code{MadbSet} object.}
    \item{\code{sample.index}:}{The index of the corresponding sample in the \code{samples} slot of the \code{MadbSet} object.}
    \item{\code{array.name}:}{The micro array name or ID.}
  }
}
\section{Methods}{
  \describe{
    \item{createNewDBTable}{\code{signature(object = "SignalChannel")}: creates a new database table that can be used to store objects from the type \code{SignalChannel} into. }
    \item{getContentMatrix}{\code{signature(object = "SignalChannel")}: returns the content of the slots of the \code{SignalChannel} object as a character matrix. }
    \item{show}{\code{signature(object = "SignalChannel")}: Displays the objects content. }
  }
