Dear Sir and Madam, 



I have a problem with the miRNA Microarray from Affymetrix.

 

I get the follow error message:

 

AffyBatch object

size of arrays=230x230 features (11 kb)

cdf=miRNA-1_0_2Xgain (??? affyids)

number of samples=9

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 installed
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/mi
rna10cdf.html> mirna10cdf and
<http://www.bioconductor.org/help/bioc-views/release/data/annotation/html/mi
rna10probe.html> mirna10probe. R und Bioconductor are installed last week,
but also in older versions it doesn’t work.

 

Thank you very much
