Hi all,
 
I have problem with the miRNA microarray from Affymetrix.       I got
the following error message:
 
> data<-ReadAffy()
> data
AffyBatch object
size of arrays=230x230 features (11 kb)
cdf=miRNA-1_0_2Xgain (??? affyids)
number of samples=5
Error in getCdfInfo(object) : 
  Could not obtain CDF environment, problems encountered:
Specified environment does not contain miRNA-1_0_2Xgain
Library - package mirna102xgaincdf not installed
Bioconductor - mirna102xgaincdf not available
In addition: Warning message:
missing cdf environment! in show(AffyBatch) 

I could not find a new package named "mirna102xgaincdf" from
BioConductor.
 
thanks
