[BioC] comparison of two sets of developmental study

[Yan Zhou]

Hi, All,

I have two microarray datasets. Each set have data from  8 different 
developmental stages( A-H, each stage have at least 3-4 biological 
replicates); The developmental stage are the same between the two; The 
only difference between the two are the tissue source. It's known that 
the two development are similar but not the same. I was wondering if 
anyone would have good suggestions as to
1. how to capture genes that are changing along development in each 
tissure seperately,
2.  and also how to capture genes behave totally different between the 
two developmental courses.

Thank you.

Yan
