[BioC] Using limma with Applied Precision SoftWorx data

[Susan J. Miller]

Does anyone have experience using limma with 2-color microarray data 
obtained from the Applied Precision SoftWorx Tracker?  I can read the 
.txt files with read.maimages but I don't know how to create a Layout 
for normalizeWithinArrays.  It seems that I should be able to map the 
Set/Set Row/Set Column values to Block/Row/Columns but I am not sure 
about this.  Any help would be much appreciated.

Thanks,
