%% Normalize Affymetrix data % This example shows how to normalize affymetrix data. The % |prostatecancerrawdata.mat| file used in the example contains data from % Best et al., 2005. % Copyright 2015 The MathWorks, Inc. %% % Load a MAT-file, included with the Bioinformatics Toolbox(TM) software, % which contains Affymetrix data variables, including |pmMatrix| , a matrix of % PM probe intensity values from multiple CEL files. load prostatecancerrawdata %% % Normalize the data in pmMatrix and plot data from columns (chips) 2 and % 3. Column 1 is the baseline. NormMatrix = affyinvarsetnorm(pmMatrix, 'Showplot',[2 3]); %% %
