Hi all,

I am interested in normalizing a matrix of PM values using
"normalize.invariantset".  So far I have only done normalization using
normalize.quantiles which accepts a matrix of PM values.

But, normalize.invariantsetdoes not asks for a vector of expression
values(x), and another vector of expression values (ref) against which to
normalize. Now, does anyone have any idea/pointers as to how to chose the
chip for the reference expression values.

Thanks,
Chiranjeet.
