Hello, I am pretty new to marray and actually having the same problem. When using read.GenePix() I get the error ""Error in if (skip > 0) readLines(file, skip) : > missing value where TRUE/FALSE needed" Additionally I get a warning message ": In greplayout.id[1], y) : Inputstring 30 not valid with this locale." When using the skip option with the number of row in the header I get "Error in `[.data.frame`(dat, , info.id) : undefined columns selected" I tried different gpr files also files downloaded from: http://genomebiology.com/2003/4/2/R9/additional/ The columns are named exactly as expected in read.GenePix() so I don't think it is a problem with the files. Here they mention that it might be a problem with R locate: https://stat.ethz.ch/pipermail/bioconductor/2005-May/008928.html Unfortunately I don't know a lot about this. My System: Ubuntu Feisty Fawn, Linux 2.6.24-23-generic i686, R version 2.8.1 (also tried older versions), Bioconductor 2.3 I would be very grateful for every help or hint. thanks a lot, J?rg

Can you mention what the output of > sessionInfo() is? Also try > Sys.setlocale(locale="C") before read.GenePix, and if that does not work try, as you start R from the command line of your operating system, % LC_ALL="C" R It would be good if you could report back to the list whether these approaches work.
