[BioC] Globaltest

[Jiuzhou song]

Hi, Fellows:

I want to try the globaltest package. The below are my data and phenotype, 
the try is 10*54000 gene expression data, phenotype is like a clinical data. 
When calling  globaltest, I got a error message said:Error: Y not among 
pData(X) variables. I don't know what's wrong. Enclosed is my organized data 
format:
>library(globaltest)
>library(hug133plus2)
>phenotype<-read.table("pdefnor.txt", header=TRUE)
>kegg<-as.list(hgu133plus2PATH2PROBE)
>cycle<-kegg[["04110"]]
>try[1:10, 1:10]

Error: Y not among pData(X) variables
>globaltest(try, phenotype, cellcycle)

is there anything wrong in my data? I greatly appreciate if any suggestion.

Thanks.
