\title{Extract the parameters of a model.}
\description{
  Extract parameters from the model into a vector of parameters for optimisation.
}
\usage{
  param <- modelExtractParam(model, only.values=TRUE)
}
\arguments{
  \item{model}{the model structure containing the parameters to be extracted.}
  \item{only.values}{include parameter names in the returned vector.}
}
\value{
  \item{param}{vector of parameters extracted from the model.}
}

  # Load a mmgmos preprocessed fragment of the Drosophila developmental
  # time series

  # The probe identifier for TF 'twi'

  # The probe identifier for the target gene
  targetProbe <- "152715_at"
