Dear BioCs,

I recently moved to a MacBook, and tried to run my usual microarray analysis
scritps (which works perfectly at my old PC), but without success.

1) RG  <- read.maimages(targets$FileName, columns = list(Rf = "F2 Mean", Gf
= "F1 Mean", Rb = "B2 Median", Gb = "B1 Median"), source="genepix",sep="\t",
 annotation = c("Block", "Row", "Column", "ID", "Name"), wt.fun=f)

Error in grep(protectMetachar(allcnames[i]), text.to.search) :
  invalid regular expression in this local

2) RG$genes <- readGAL ("name_of_the_file.gal")

object of the type 'closure' not possible to divide in substes

Any ideas? What am I missing?

Here is my session info:
