Hi and thanks for your response, actually topTable and works if the object that I have is a MArrayLM object but. The problem is that I have an object "Bgene" which is a list and includes all the columns of interest.I am sorry that I wasn't clear.I have already generated the results but I also tried decideTests in case I could generated them in an other way to get all the FDRs and fold changes for each gene. > class(Bgene) [1] "list" > names(Bgene) [1] "ttAll" "DownSameUp" > names(Bgene$ttAll) [1] "T11" "T3" "T19" "T19_T11" > names(Bgene$ttAll[1]) [1] "T11" > names(Bgene$ttAll[[1]]) [1] "Row" "Column" "Block" "Name" "ID" [6] "Reps" "ARKcloneID" "Status" "M" "A" [11] "t" "P.Value" "adj.P.Val" "B" "FoldChange" [16] "FDRmax" "FDR" "FDRup" "FDRlow" For example, I want to get all the FDr for time point T11 with the respective gene name FDR11<-(Bgene$ttAll[[1]])$FDRmax the problem is that I don't get the respective gene names automatically when I do that and when I assign rownames(FDR)<-sort(unique(MA$genes$ARKcloneID)) I get an error message that I assign it to something with no dimension which is true because it is not a matrix but a list!!
