Normalization problem
At first I would like to express the gratitude toward Oosting, J. and James
MacDonal for their help solving the previous problem I posted on this forum.
Now I have a new problem. I was trying to normalize set of microarray data
on HGU133 paltform. I put all the HGU133A platform chips in one directory
and all the other HGU133B chips on another directory. When I tried to
normalized them using same script HGU133A data worked fine but got error for
HGU133B platform data. The code is

how to map microarray probe to gene, homology
Hi:
I have clustered microarray gene expression data and trying to map between
microarray probe, gene, pathway, gene ontology, and homology for a set of
(affy) microarray probes. Is there any package in R which facilitates this?
I am looking at bioconductor, but till now could not find a solution. A
link to some worked example would be appreciated.
Thanks and regards.
John
