[BioC] Layout in limma

[Binita Dutta]

Hi All,

I have gene description of microarray in text file (not the GAL file as 
given for the swirl example in limma package) and the data set is also in 
the text file. As i undertsnad there are no facilities for importing 
marrayRaw objects into limma. I want to analyse the whole data in limma for 
the color flip experiments. I can import the data for analysis in limma 
package but have not been able to feed in the layout of my array. Please 
let me know how to do this. I have 2 "grid columns" and 12 "grid rows". 
Within each grid there are 45 "spot columns" and 21 "spot rows". Is there 
anythng similar to "widget.marrayLayout()" in limma package?

Thanks in advance.
