Hello Bioconductor list;
 
    I'm currently looking at some Rat Gene 1.0 ST arrays. I get an error when I try to rma normalize a data set of Rat Gene 1.0 ST cel files. The code is following:
 
library(affy)
library(annotate)
a1<- ReadAffy(filenames = my.filenames)
rma(a1)
 
The error message produced by R is following:
Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered:
Specified environment does not contain RaGene-1_0-st-v1
Library - package ragene10stv1cdf not installed
Data for package affy did not contain ragene10stv1cdf
Bioconductor - ragene10stv1cdf not available
 
My question is where to find the ragene10stv1cdf and how to obtain CDF environment? Thanks.
 
 
Cunye
