Gquantile

This method ensures that the green (first) channel has the same empirical distribution across arrays, leaving the $ \mathbf{M}$-values (log-ratios) unchanged. This method might be used when the green channel is a common reference throughout the experiment. In such a case the green channel represents the same target throughout, so it makes compelling sense to force the distribution of intensities to be same for the green channel on all the arrays, and to adjust to the red channel accordingly [5].
