Hi everyone, I practiced using "Analysing Illumina bead-based data using beadarray by Richie & Dunning with the SAMExample dataset. However, when exploring my own beadarraydata I found that my raw data files are txt files and not csv (as they were in the practical). I was able to read the metrics.txt file (this file gives me the date of analysis, beadchip, section...etc), but when I try to use: BLData = readIllumina(arrayNames = metrics$arrayID, textType = ".txt", metrics = metrics, backgroundMethod = "none") I get this response: Found 0 arrays Error in seq.default(1, length(tmp), by = 3) : wrong sign in 'by' argument I've tried replacing arrayID with Beadchip, since it is used in the metrics file, and still it gives me the same message. There should be 24 arrays. Is there another function to read the arrays in R?

Dear Hajar, If this is the same data you mailed the list about the other day, make sure the 'arrayNames' you are specifying are the full names (probably something like '5513091009_A_1_perBeadFile.txt', '5513091009_A_2_perBeadFile.txt' for your first sample if you have WG-6 BeadChips, etc.) Also make sure that all of these files are available in the current working directory - you can check this with dir(pattern="*perBeadFile.txt") If they aren't, change the working directory using the setwd() function.
