Hello,
I'm using the affy package for the first time. However, the current version
of the affy package doesn't include  Affymetrix's MoGene cluster annotation
version 2.0. Could you please point out the correct way of re-constructing
the annotation packing using the original annotation from the
manufacturer's site? For example, the current version throws the following
error message:

*Produces the following error:

*
*background correction: mas
PM/MM correction : mas
expression values: mas
background correcting...Error in getCdfInfo(object) :
 Could not obtain CDF environment, problems encountered:
Specified environment does not contain MoGene-2_0-st
Library - package mogene20stcdf not installed
Bioconductor - mogene20stcdf not available*


I'd appreciate any help and thank you for your time.

Best,
Paul
