Hi I was wondering if you can read a tab delimited file of micro array data using readCtData() in HTqPCR as follows: Detector SampleA SampleB etc. Gene1 20 23 Gene 2 32 25 etc. I've tried foo <- readCtData('file.txt', header=T, n.features=381, samples=samples, n.data=27) # in this case there are 381 rows of Detectors and 27 samples But get the following error message: > foo <- readCtData('PCM_cardA-all-raw.txt', header=T, n.features=381, samples=samples, n.data=27) Error in `[<-.data.frame`(`*tmp*`, undeter, value = "Undetermined") : only logical matrix subscripts are allowed in replacement In addition: Warning messages: 1: In readCtData("PCM_cardA-all-raw.txt", header = T, n.features = 381, : 381 gene names (rows) expected, got 381 2: In matrix(sample[, Ct], ncol = n.data[i]) : data length [381] is not a sub-multiple or multiple of the number of rows [15] Thanks, Andrew > sessionInfo() R version 2.12.2 (2011-02-25) Platform: x86_64-unknown-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=C LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=en_US.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] HTqPCR_1.5.4 limma_3.6.9 RColorBrewer_1.0-2 Biobase_2.10.0 loaded via a namespace (and not attached): [1] affy_1.28.0 affyio_1.18.0 gdata_2.8.1 [4] gplots_2.8.0 gtools_2.6.2 preprocessCore_1.12.0 [7] tools_2.12.2

However, if you simply have your data in a tabular format, you can create your qPCRset object manually like this: # Reading in all values temp <- read.delim('PCM_cardA-all-raw.txt') # Making pesudo-data, just to illustrate the example temp <- matrix(sample(12:40, size=27*381, replace=TRUE), ncol=27) rownames(temp) <- paste("gene", 1:381) colnames(temp) <- paste("sample", 1:27) # Make qPCRset object q.raw <- new("qPCRset", exprs=temp, featureNames=rownames(temp), sampleNames=colnames(temp), flag=as.data.frame(array("Passed", dim=dim(temp))), featureCategory=as.data.frame(array("OK", dim=dim(temp)))) If this doesn't work with your data for some reason, then please let me know.

Thanks, that works!

I'm having the same issue, and the example with pseudo data does (same for my own data) not work for me:

# Making pesudo-data, just to illustrate the example temp <- matrix(sample(12:40, size=27*381, replace=TRUE), ncol=27) rownames(temp) <- paste("gene", 1:381) colnames(temp) <- paste("sample", 1:27) # Make qPCRset object q.raw <- new("qPCRset", exprs=temp, featureNames=rownames(temp), sampleNames=colnames(temp), flag=as.data.frame(array("Passed", dim=dim(temp))), featureCategory=as.data.frame(array("OK", dim=dim(temp))))

> q.raw <-new('qPCRset', exprs=temp, featureNames=rownames(temp),sampleNames=colnames(temp), flag=as.data.frame(array('Passed', dim=dim(temp))), featureCategory=as.data.frame(array("OK", dim=dim(temp))))
Error in (function (storage.mode = c("lockedEnvironment", "environment",  :
  'AssayData' elements with invalid dimensions: 'featureNames' 'sampleNames''AssayData' elements with different rowNames

I also run into the exactly same problem!
Did you find a solution to that?
