\title{ Read user formatted qPCR data and produce a qPCRBatch }
\description{
  Reads RT-qPCR data in format specified in the ReadqPCR vignette and uses the data to populate an object of class
  \code{"qPCRBatch"}.
}
\usage{
read.qPCR(filename = character(0),
          phenoData = new("AnnotatedDataFrame"),
          notes = "",
          verbose = FALSE)
}
\arguments{
  \item{filename}{file name (must be formatted as shown in vignette).}
  \item{phenoData}{an \code{\link[Biobase:class.AnnotatedDataFrame]{AnnotatedDataFrame}}
     object, a \code{character} of length one, or a \code{data.frame}.}
  \item{notes}{notes.}
  \item{verbose}{verbosity flag. If true more messages are given to the user on the processing steps}
}
\details{
  Permits the user to read in qPCR Cq value data in a predefined format 
  (more details on this format in the \code{ReadqPCR} package vignette), alongside 
  phenotypic data and further notes about the data. If \code{phenoData} is a \code{data.frame}, 
  it is converted to an \code{AnnotatedDataFrame}. If it is \code{NULL} then a default object
  of class \code{AnnotatedDataFrame} is created, whose \code{pData} is a
  \code{data.frame} with rownames being the names of the samples, and
  with one column \code{sample} with an integer index. 
  More details on how technical replicates are handled in the \code{ReadqPCR} package vignette
