I found these papers helpful as starting point: http://www.biomedcentral.com/1471-2105/8/221 http://bioinformatics.oxfordjournals.org/cgi/content/full/25/7/954 http://www.biomedcentral.com/1471-2105/8/219 However, I use the limma package from R to get the data in shape (background subtraction, normalization). Than I make a gff file out of the data and use CoCAS to detect the peaks. This might not be the best way (any better suggestions are welcome) since I'm as well a beginner rather than an expert. Good luck, Torsten -----Original Message----- From: bioconductor-bounces@stat.math.ethz.ch [mailto:bioconductor-bounces at stat.math.ethz.ch] On Behalf Of Daofeng Li Sent: 26. juni 2009 10:33 To: bioconductor at stat.math.ethz.ch Subject: [BioC] help on analysis ChiP-chip data of affyymetrix Arabidopsistilling array Dear list members, i am totally new to this area can anyone recommend some material for me to study?

I believe w/ bioconductor 2.4 came an rMAT package, which is an implementation of this software in R if you'd like to try it that way: http://www.bioconductor.org/packages/release/bioc/html/rMAT.html Hope that helps, -steve -- Steve Lianoglou Graduate Student: Physiology, Biophysics and Systems Biology Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos
