I am trying to intermingle two timeseries expression data from two different platform (affymatrix and cDNA array).To follow a common index system, I mapped the probesets and cDNA clones (from above given platforms, respectively) to unique entrez Ids. Only common Ids are retained (~7500).
How can I integrate or compare these two datasets together at intensity level?
