I would like to use microarray data from GSE2034 but I can't find the method of normalization of that. So, I downloaded the paper of that data (Gene-expression profiles to predict distant metastasis of lymph-node-negative primary breast cancer). In gene expression analysis section of that paper, the authors wrote that " Expression values were calculated by use of Affymetrix GeneChip analysis software MAS 5.0." My, Question is, can I assume that the method of normalization of GSE2034 data set is 'MAS 5.0'? or it can have another normalization methods such as 'RMA'?
I appreciate if anybody share his/her comment with me?
