Chip type: RaGene-1_0-st-v1

Rat Gene 1.0 ST Array

RaGene-1_0-st-v1.r3

Note, the CDF downloaded from the Affymetrix website is in an ASCII (text) file format. It is highly recommended to work with binary CDFs instead since they are orders of magnitude faster to query and more memory efficient to work with. Use convertCdf() in the affxparser package to convert an ASCII CDF into binary.
