Hi, everyone:

 

I am just starting using Bioconductor Affy package. I have CEL file and
after read them, I got the error massage:

 

>raw<-readaffy(),

>raw

Error in getCdfInfo(object) : Could not obtain CDF environment, problems
encountered:

Specified environment specified did not contain Mapping10K_Xba142

Library - package mapping10kxba142cdf not installed

Data for package affy did not contain Mapping10K_Xba142

Bioconductor - mapping10kxba142cdf not available

AffyBatch object

size of arrays=658x658 features (20301 kb)

cdf=Mapping10K_Xba142 (??? affyids)

number of samples=6

Warning message:

missing cdf environment ! in: show(list()) 

Note: Using download type: Win32 

Error in getCdfInfo(object) : Could not obtain CDF environment, problems
encountered:

Bioconductor - mapping10kxba142cdf not available.

 

As was pointed out, Bioconductor does not contain the mapping10KXBa cdf
file, my library does not contain the cdf file either.   I tried to
install it by downloading the corresponding library from affy
(10K2_libraryfile.zip,   but don't know how to install it in R. 

 

 

I know this may sound  routine for somebody, but it frustrated me a lot,
like....a blind person stumbling for a way out of darkness.....

 

Thanks very much for your help. It means a lot of my time  being saved. 

 

Jacob
