Dear list,
I have expression data with Affymetrix hg u133 plus 2 probeset IDs &
gene set data with gene names. So both gene set and expression data
are not using the same gene ID system which is a requirement to run
the GAGE analysis.
So the problem is that if i convert the Probeset IDs to gene name, i
get a single gene name for multiple probes. So the expression data
will now have multiple rows with same gene name. IS THIS VALID IN
GAGE? How the GAGE package tackles this problem? & If i want to
convert the gene names in gene set to Affymetrix hg u133 plus 2
probeset IDs then the problem is WHICH probeset ID should i choose if
multiple probeset IDs are associated with that gene.
Thanks,
Jung
