Hello everyone! I am looking for methods to put out the normalization result. I used limma to do the normalization. I found out the command in R's document, write.table. But I don't know how to use it. Could anybody teach me? Thank you very much! -- Xiaopeng ZHANG<xpzhang@genetics.ac.cn>

You can use: getwd() to see your current directory, and setwd("C:/Microarray/NormalizationResults") to change your current directory. (Forward-slashes are better than back-slashes if you are a Windows user.) Then to write tab-delimited text files, try this: The first method writes the M values including an initial column containing row names of the R matrix MA$M: write.table(MA$M,file="Mvalues.txt",sep="\t",col.names=NA) The second method omits the row names: write.table(MA$M,file="Mvalues2.txt",sep="\t",row.names=FALSE) You can do the same thing for MA$A. Hope this helps, James
