How do I convert the row names of the intensity value ("1007_s_at" "1053_at" "117_at" "121_at" "1255_g_at")
from the HG-U133_Plus_2 Affymetrix Human Genome U133 Plus 2.0 Array to gene names from the official CDF? This there a online tutorial somewhere? Thanks

You can use some web tools, e.g. DAVID Resources Converter.
