hello.... i am using affymlmGUI for microarray analysis and finally i got top 50 genes which are up regulated. i got a file in which *ID M A t P.value and B *column are present. can anyone tell me what is M and A??? regards deepika [[alternative HTML version deleted]] _______________________________________________ Bioconductor mailing list Bioconductor@r-project.org https://stat.ethz.ch/mailman/listinfo/bioconductor Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor [[alternative HTML version deleted]]

While I've never used this package, my *guess* is that these are the same M and A that are used in MA plots, where M is the log fold change of the gene's expression in your two samples, and A is the mean expression of the two genes in the samples.
