To: bioconductor at stat.math.ethz.ch Message-ID: <cedaa40b0706212318w8c6a7afhbef762c4572995b3 at="" mail.gmail.com=""> Content-Type: text/plain Dear all, I have two samples(affymetrix expression array,so two CEL files),before and after drug treatment.I can get Fold change when applied RAM normalization procedure.It seems that GCOS has a probe level comparative analysis method on two samples.And is there a similar fuction in bioconductor?
