Hello, I hope anyone can help me with my problem. I want to read in data from SMD files. When I use read.SMD I get the following error: > shyamSMD <- read.SMD(fnames=file,layout=galinfo$layout,gnames=galinf o$gnames,targets=shyamTargets,skip=22) Fehler in 1:dim(maInfo)[1] : NA/NaN Argument Therefore I took the intensities out of the SMD files and put them in extra files to be able to use read.marrayRaw. But then I get the following error: > shyam.raw <- read.marrayRaw(fnames=files,name.Gf="gfmedian",name.Gb= "gbmedian",name.Rf="rfmedian",name.Rb="rbmedian",layout=galinfo$layout ,gnames=galinfo$gnames,targets=shyamTargets,DEBUG=TRUE) [1] "in read.marrayraw" Path . NULL [1] "In is.null(skip) " 0 done [1] "nspots = 44544" Reading ... ./data_14621.xls [1] "in is.null(skip), part 2" Calculating skip ... 0 done Fehler in "[<-"(`*tmp*`, , f, value = c(752, 632, 7172, 231, 1898, 523, : Anzahl der zu ersetzenden Elemente ist kein Vielfaches der Ersetzungsl?nge The last part means: error in "[<-"(`*tmp*`, , f, value = c(752, 632, 7172, 231, 1898, 523, : number of elements that should be replaced is not a multiple of the replacement length I then thought I have to skip the first line with the column names, but then I also get the error that not defined columns where chosen. Can anyone help me and tell me what to do to read in the data? Thanks, Jenny

Hi Jenny, If you send me an example file off-list. I will take a look at your problem.
