[BioC] ad hoc tools for affy tiling arrays?

[Kasper Daniel Hansen]

In a a sense tiling arrays are more general tools than expression  
arrays. What you are looking for (and hence your method of analysis)  
is (or at least should be) dependent on your research question. In  
comparison, with an expression array you are interested in genes that  
are DE between different experimental conditions.
