\title{Summarize cell features}

\description{
  Compute phenotypic profiles by summarizing cell population features.
}

\usage{
summarizeWells(x, uname, featurePar, profileFilename="data/profiles.tab", access='cache')
}

\arguments{
  \item{x}{An imageHTS object.}
  
  \item{uname}{A character vector, containing the well names to
    summarize. See \code{getUnames} for details.}
  
  \item{featurePar}{A character string, indicating the filename
    containing the feature extraction parameters.}

  \item{profileFilename}{A character string, indicating the output filename
    to store the phenortpic profiles.}
  
  \item{access}{A character string indicating how to access the
    data. Valid values are \code{local}, \code{server} and \code{cache},
    the default. See \code{fileHTS} for details.}
}

\value{
  A data frame, containing the phenotypic profiles.
}

\details{
  \code{summarizeWells} computes for each well, summary statistics
  about cell features. Currently, cell number \code{n} and
  median cell feature \code{med.*} (for each feature) are computed.

  Moreover, if the DCF segmentation parameters file pointed by
  \code{featurePar} includes the field \code{cell.classes}, containing
  a list of comma-separated cell classes, cell classes ratio are computed
  and included in the phenotypic profiles.

  \code{summarizeWells} creates the file \code{data/profiles.tab}
  which contains the phenotypic profiles. Use \code{readHTS} to
  read this file.
