Dear list members,

I am seeking advice in following. I have results of a time-course microarray experiment, essentially an lmFit where every time point is compared to starting point. Now, I would like to see if I can find the chromosome regions where gene expression changes over time in coordinate manner. I was thinking of using one of the aCGH analysis packages, particularly snapCGH. Is it reasonable to use it with expression data? Assuming that I could use this package for my analysis, how could I adjust it to work with Drosophila chromosomes? The examples in User's guide deal with human, and I couldn't find where and how I can change to different organism, or define the chromosome properties.
