Hi Leutz, Thanks for your interest in GAGE. For your question, GAGE decomposes group-vs-group comparison into sample-vs-sample (pair-wise) comparison. You need to specify control and treated sample column indices using 'ref' and 'samp' arguments. The following code chunk show you some example run on your data. Check the help information of 'gage' function and the package vignette for more details. HTH. Weijun library(gage) library(gageData) #1 time point cn=colnames(yourArrayData) c1=grep(' c1',cn, =T) t1=grep('t1',cn, =T) gse16873.kegg.p = gage(yourArrayData, gsets =, ref = c1, samp = t1) #you need to specify argument compare = "unpaired" if your c1 and t1 samples are not paired (1-on-1 matched) by design. #multiple time points altogether refList=list(c1, c8, c16, c24) sampList=list(t1, t8, t16, t24) sampnames=pc("t1vsc1","t8vsc8","t16vsc16","t24vsc24") gagePipe(yourArrayData, gsname = "", dataname = "yourStudy", sampnames = sampnames, ref.list = refList, samp.list = sampList) #again, you need to specify argument compare = "unpaired" if your control and treated samples are not paired. --- On Sun, 7/24/11, Leutz Buon <lb089 at=""""> wrote: > From: Leutz Buon <lb089 at=""""> > Subject: Biological replicates with Gage > To: "Weijun Luo" <luo_weijun at=""""> > Date: Sunday, July 24, 2011, 8:01 PM > > Hi, > I'm doing a gene set analysis with GAGE.
