\description{

  group names that remain the same as long as no re-grouping occurs.

\arguments{
  \item{object}{the \code{xcmsSet} or \code{xcmsEIC} object}
  \item{mzdec}{number of decimal places to use for m/z}
  \item{rtdec}{number of decimal places to use for retention time}
  \item{template}{
    a character vector with existing group names whose format should
    be emulated
  }
}
\value{
  A character vector with unique names for each peak group in the
  object. The format is \code{M[m/z]T[time in seconds]}.
