}
\usage{

	columns=c("SPECTRUM","RETENTION_TIME_INDEX","RETENTION_TIME"))

bin2text(in.files, out.files=NULL)
}
\arguments{
	\item{in.files}{A character string naming the input files. }

	\item{out.files}{A character string naming the output files. If
		\code{NULL}, the input file extensions will be changed
		accordingly ("txt" to "dat" and viceversa).}

	\item{columns}{A numeric vector with the positions of the columns
		\code{SPECTRUM}, \code{RETENTION_TIME_INDEX}, and
		\code{RETENTION_TIME} or a character vector with the header
		names of those columns. This parameter is required only
		for \code{text2bin}.}
