Hi,
I was trying to compare differential expression data
from multiple studies ( 4 dataset downloaded from NCBI
GEO). The expression dataset are from Affy, as well as
cDNA (dual channel) platforms. Before I conduct
analysis, I have to map the gene IDs so that the
different genes are comparable.
Which packages, and what commands do I need for this?
Take a look at the Bioconductor project:
