Hi all,

I'm using Agilent Yeast Whole Genome ChIP on chip platform.  
Unfortunately, very few tools are available for this platform. I  
began to analyze my data with the limma package, but now I am faced  
to a problem.
I'd like to plot the values of each probe enrichment (ratio) on the  
chromosome. I tried to use the plotChr function from the geneplotter  
package. This function needs the argument "senseObj" created by the  
function Makesense. The function Makesense needs an ExpressionSet  
(which I've created), and a Bioconductor annotation data package  
(called "lib"). The problem is that there isn't such package for the  
arrays I'm using. Does it mean that I cannot visualize my data on  
chromosomes, or is there something I don't understand?

Thanks

Yad
