Hi All,
I did a test run of Limma looking at the user's guide,
on using the normalizeWithinArrays() function, I got a
subscript out of bounds error. The steps I follwed
were

> files <- dir(pattern="*\\.gpr$")
> RG <- read.maimages(files, source="genepix")
Read result1.gpr 
Read result2.gpr 
Read result3.gpr 
Read result4.gpr 
Read result5.gpr
> RG$genes <- readGAL()
> RG$printer <- getLayout(RG$genes)
> MA <- normalizeWithinArrays(RG)
Error: subscript out of bounds

The gpr files I used were not modified and I did not
filter out the bad spots.
What could be the problem here and how do I solve it?
Looking forward to a reply,
-Ankit
