[BioC] Error "Specified environment does notcontain MoGene-1_0-st-v1"

Hello all,
Another (valid) way to still use the affy library is utilizing the MBNI Custom CDF-files:
http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/11.0.1/entrezg.asp <http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/11.0.1/entrezg.asp> 
The libraries "mogene10stv1mmentrezgprobe" and "mogene10stv1mmentrezgcdf" are compatible with the affy-library, although normalization methods that utilize mismatch probes (like gcRMA and MAS5) won't work. If you apply normalization (e.g. rma or vsn), be careful with what you'll get.
So you can load the .CEL-files as follows (after installing these libraries):
x <- ReafAddy(cdfname="mogene10stv1mmentrezg")
Annotation libraries for the most popular MBNI Custom CDF-files can be found here: http://nugo-r.bioinformatics.nl/NuGO_R.html

Although the affy package can read these data in, it won't be able to
process the data without extra (unnecessary) work from you, as the affy
package wasn't designed to analyze these chips. Please see here:


For a listing of packages that are designed for this chip.
