[BioC] error with pd.ragene1.0.st.v1 and oligo

[Ian [guest]]

Hi,

I am analyzing some rat arrays. I get this error:

Error in validObject(.Object) : 
  invalid class “GeneFeatureSet” object: featureNames differ between assayData and featureData
Calls: hist ... assayData<- -> assayData<- -> .init_NChannelSet -> validObject

I am pretty sure my code is close to correct as I put together this script to analyze the pd.rat230.2 arrays for another project and it worked great.

Now I have switched to a project that used the pd.ragene.1.0.st.v1 instead and now I am getting this error and am in need of figuring it out again.

Any pointers would be great.

Thanks,

Ian
