Hello,

I am new to the marray package and I am using it to read .GPR files. Here is
the sequence of commands that I entered and the resulting error:
> library(marray)
Loading required package: limma
> datadir <- "P:/Manually flagged"
> pigTargets <- read.marrayInfo(file.path(datadir, "JG2.7 target file.txt"))
> mraw <- read.GenePix(targets=pigTargets, path = datadir)
Error in "row.names<-.data.frame"(`*tmp*`, value = c("1", "1", "1", "1",  :
        duplicate 'row.names' are not allowed
>

Our microarray data includes duplicated genes and therefore, duplicated gene
names and this could be what is causing the error. Is there anyway to
bypass/fix this?
Thanks for your help.

Andre
