Dear Sean and other,
I'm using an oligo microarray slide, and I used the ScanArray Express
software to generate a .csv file.

This is my layout:

> RG$printer
$ngrid.r
[1] 12

$ngrid.c
[1] 4

$nspot.r
[1] 23

$nspot.c
[1] 24

attr(,"class")
[1] "PrintLayout"

So, apparently, the NormalizeWithinArrays function should  be able to
understand my layout.

Just to remember you, I tried this:

> MAp = normalizeWithinArrays(RG.mb)
Error in switch(method, loess = { :
  printer layout information does not match M row dimension

Thanks again.

Priscila
