Plot of mean log2 difference versus mean log2 intensity (MA plot) when all probesets are normalized

MA plot for high intensity probesets when all probesets are normalized (grey) and when only the high intensity probesets are used after cel file masking (black). Normalization method is GC-NSB correction, loess probe-level normalization, medianpolish summary and vsn probeset-level normalization.<p><b>Copyright information:</b></p><p>Taken from "Estimation and correction of non-specific binding in a large-scale spike-in experiment"</p><p>http://genomebiology.com/2007/8/6/R126</p><p>Genome Biology 2007;8(6):R126-R126.</p><p>Published online 26 Jun 2007</p><p>PMCID:PMC2394775.</p><p>
