Dear BioC,

we have a microarray experiment design for which we will retrieve more
samples in future.
To have consistent analysis I would like to set a reference sample in
dataset now available,
and then use it for also for later experiments.
We are using affymetrix platform, so I would like to know if any
normalization implemented in affy permits this operation, and how to do
this.

I know Dchip permits to make this choice, so I guess the Invariant set
implementation should give this opportunity, but I did not find out how to
to this.

thank you
