Dear R users, I am using the beadarray package. I am trying to upload raw bead-level data using these commands: ######################################################## library(beadarray) datadir <- ("C:/Computer_programs/R/beadarray/cecilia") targets = read.table("targets.txt", sep = "\t", header = TRUE, as.is = TRUE) BLData = readIllumina(arrayNames =NULL, useImages=TRUE, singleChannel=FALSE, backgroundMethod ="rma", annoPkg= NULL, metrics=FALSE, metricsFile="Metrics.txt", normalizeMethod="quantile", tiffExtGrn="_Grn.TIF", tiffExtRed="_Red.TIF") #################################################### After the above last command (4th one), I got this error message: #################################################### Found 96 arrays Error in order(dat1$ProbeID) : object 'dat1' not found In addition: Warning message: In readIllumina(arrayNames = NULL, useImages = TRUE, singleChannel = FALSE, : No annotation package was specified. Need to use SetAnnotation later ###################################################### I will appreciate help to troubleshoot this error. Thank you very much. Roger Roger L.

Dear Roger, Error in order(dat1$ProbeID) : object 'dat1' not found it may be unable to scan your files, you should compile line by line the readIllimna program: if (useImages) { tifFiles = vector(length = length(arrays)) tifFiles = file.path(path, paste(arrays, tiffExtGrn, sep = "")) for (i in 1:k) { file = csv_files[i] if (csvNcol == 4) { fc = file(file, open = "r") dat1 = scan(file = fc, what = list(ProbeID = integer(0), NULL, GrnX = numeric(0), GrnY = numeric(0)), sep = sep, dec = dec, skip = 1, quiet = TRUE) close(fc) } else if (csvNcol == 7) { fc = file(file, open = "r") dat1 = scan(file = fc, what = list(ProbeID = integer(0), NULL, GrnX = numeric(0), GrnY = numeric(0), NULL, RedX = numeric(0), RedY = numeric(0)), sep = sep, dec = dec, skip = 1, quiet = TRUE) close(fc) } else if (csvNcol == 6) { fc = file(file, open = "r") dat1 = scan(file = fc, what = list(NULL, ProbeID = integer(0), NULL, NULL, GrnX = numeric(0), GrnY = numeric(0)), sep = sep, dec = dec, skip = 1, quiet = TRUE) close(fc) RedX = dat1$GrnX RedY = dat1$GrnY } * ord = order(dat1$ProbeID) /* error message*/* you have warning message because annoPkg option is NULL Best Regards Mohamed Vallejo, Roger a ?crit : > Dear R users, > > I am using the beadarray package.
