Dear Joao, See ?plotPrintorder and http://www.statsci.org/smyth/pubs/porder/porder.html. (I'm a bit puzzled why you haven't already tried this, considering that you're already using limma and are aware of printorder effects.) Note that GAL file order is not the same as printorder in general, so you can't just use plot().

Hi Gordon, FYI - I was playing around with plotting print order effects, and found a discrepancy between the help documentation and the actual behavior of 'normalizeForPrintorder.rg '. The help file states "The function plotPrintorder or normalizeForPrintorder.rg with plot=TRUE returns no value but produces a plot as a side-effect." However, when I used 'normalizeForPrintorder.rg' with plot=TRUE, it not only produced the plot but spit out the entire list! I'm using this function instead of the wrapper 'plotPrintorder' because I'm having trouble making the necessary layout list. I could only find a little bit of information about the layout list in 'printorder' help page - is each component of the list (ngrid.r, ngrid.c, nspot.r and nspot.c) just a single number? In my case our printer has 48 tips and prints 12 x 4 blocks of 420 spots, one dip per spot, so would my layout just be a list of ngrid.r = 12, ngrid.c = 4, nspot.r = 420, and nspot.c = 1?

Dear Jenny As I recall, ngrid.r & ngrid.c are the number of grid rows and columns, so 12 and 4 in your case, while nspot.r & nspot.c are the number of spot rows and columns within each grid block, probably 20 and 21 for you. I don't think the number of dips per spot is taken into account. HTH \Heidi > ...I could only find a little > bit of information about the layout list in 'printorder' help page - is each component of the list (ngrid.r, ngrid.c, nspot.r and nspot.c) just a > single number?

You also need to know the number of rows (nspot.r) and columns (nspot.c) of spots in each block. nspot.c is almost certainly greater than 1. You also need to check with your microarray printing unit whether printing of your arrays begins in the top right or top left of each block, and whether it proceeds by rows or columns. The default for normalizeForPrintorder assumes topleft by rows, which the usual setup at UCSF. But the AGRF in Australia uses topright by rows. See help("PrinterLayout-class"). The read.maimages() function produces the printer layout information automatically as RG$printer for some input sources including GenePix and ImageGene.

Hi Gordon, Thanks for your help. Here's one correction for the archives and a small suggestion: >See help("PrinterLayout-class"). this should be help("PrintLayout-class") >The read.maimages() function produces the printer layout information >automatically as RG$printer for some input sources including GenePix and >ImageGene. The PrintLayout class help page does explain everything pretty well, and I was happy to see that I already had RG$printer because I had GenePix data. I would suggest a small change to the help page of Print-Order Normalization, that the argument 'layout' wants an object of class 'PrintLayout' (or a similar list). That would have helped me make the connection and find the information.

Dear Joao, I don't remember how I made the anova table. The information can be obtained from two one-way anovas and I probably made the table by hand.
