\title{FAAH knockout LC/MS data xcmsSet}
\description{
  \code{xcmsSet} object containing quantitated LC/MS peaks from the
  spinal cords of 6 wild-type and 6 FAAH knockout mice. The data is a
  subset of the original data from 200-600 m/z and 2500-4500 seconds.
  It was collected in positive ionization mode.
