Dear Mark, Thanks for sharing "lumidat" package with me. I think it works fine now. But I'm wondering if an argument "convertNuID" is available in lumiR.idat(). When I ran it it failed with error like following. > res<-lumiR.idat(filenames,manifestfile="HumanHT-12_V4_0_R1_15002873_B.txt",na.rm=TRUE,probeID="NuID",convertNuID=TRUE) java -Xmx1024m -jar /Library/Frameworks/R.framework/Versions/2.15/Resources/library/lumidat/bin/IlluminaGeneExpressionIdatReader-1.0.jar -outputDir /var/folders/q6/hny37vrd5wx_77gpj71ng3cw0000gn/T//RtmpHnCFD6 -bg false -collapse none -manifestfile HumanHT-12_V4_0_R1_15002873_B.txt '8473515005_A_Grn.idat' '8473515005_B_Grn.idat' '8473515005_C_Grn.idat' '8473515005_D_Grn.idat' '8473515005_E_Grn.idat' '8473515005_F_Grn.idat' '8473515005_G_Grn.idat' '8473515005_H_Grn.idat' '8473515005_I_Grn.idat' '8473515005_J_Grn.idat' '8473515005_K_Grn.idat' '8473515005_L_Grn.idat' iDAT files: [8473515005_A_Grn.idat, 8473515005_B_Grn.idat, 8473515005_C_Grn.idat, 8473515005_D_Grn.idat, 8473515005_E_Grn.idat, 8473515005_F_Grn.idat, 8473515005_G_Grn.idat, 8473515005_H_Grn.idat, 8473515005_I_Grn.idat, 8473515005_J_Grn.idat, 8473515005_K_Grn.idat, 8473515005_L_Grn.idat] Wrote: Sample Probe Profile.txt Wrote: Control Probe Profile.txt Error in lumiR(files[1], detectionTh = detectionTh, na.rm = na.rm, convertNuID = FALSE, : formal argument "convertNuID" matched by multiple actual arguments If I remove convertNuID=TRUE, it works fine but featureNames are defined by ProbeID. After I read this I want to play with matrix generated by "exprs()" and rownames is always same with probeID. There is an another argument in lumiR.idat, probeID. However, there is no changes when I select ProbeID or NuID. I want the rownames are NuID or EntrezID at the end. And can you please let me know how I can do it?

There's no compiled code (java handles the decryption), so it's easy to install on linux or mac. I've used it on hundreds of arrays, so please contact me if you're interested in testing it out. cheers, Mark On 28/08/2012, at 9:20 AM, Kasper Daniel Hansen wrote: You / we / someone should consider wrapping this into a more easy to install package, together with crlmm::readIDAT (and in case there are other Illumina parsing functions around, they could be included as well). What is the license for openssl?

The reliance on third party libraries is why I've not submitted it to Bioconductor, so they may be causing problems. I'm not sure why you're using source(), rather than loading the package via library(). Have you installed the package, or just unzipped it and grabbed the .R file? It need to be installed in order to build the DLL and link against the decryption routines. To do that you need to download the tar.gz from the website you linked to and then run R CMD INSTALL IDATreader_0.1.1.tar.gz in a terminal to installed the package. You then need to load it using library(IDATreader) in your R session, rather than using source(). Hopefully that's of some help, Mike On 22 August 2012 23:35, Yoo, Seungyeul > wrote: Hi all, I'm trying to analyze Illumina array of gene expression. The file format is .idat which is encrypted data.
