spikeInData
(Package: les) :
Spike-in ChIP-chip data set
This data set is part of a quality control study for tiling microarrays (Johnson et al., 2008), in which spike-ins were used to assess the influence of microarray platforms, preparation procedures, and analysis algorithms on the accuracy and reproducibility of ChIP-chip experiments. Here, the expression intensities of one region from the 'undiluted' data set investigated with Affymetrix arrays is selected, consisting of 452 probes and two conditions with three replicates each. The data has been normalized using quantile normalization and probe positions remapped to a common reference.
