Hi, I have normalised my two channel arrays with loess and the output file calles MA object (i named as MA.loess) was saved. When i gave the command names(MA.loess), i saw it has the following rows [1] "targets" "genes" "source" "printer" "M" "A" I was trying to transfer it to a text file to go on with differential analysis and clustering since one week, but im failed always. Please kindly help me....i want to have the log ratios of all genes and all arrays to do cluster analysis. I have tried with write.table, but didnt worked... Kind Regards -- Raju Kandimalla, PhD student Erasmus MC

You'll need to read the posting guide ( http://bioconductor.org/docs/postingGuide.html) and follow those instructions when posting to the list. In particular, you will need to give us your sessionInfo() and the code you used that "did not work". To answer your question, though, write.table is the correct function, though.
