[BioC] Trying to convert to ExpressionSet object problems

[Daniel Brewer]

Hello,

I am having trouble converting an exprSet to an ExpressionSet.

> U95B <- justGCRMA()
... Add various bits to the pheno data and change the name of the samples
> class(U95B)
[1] "exprSet"
attr(,"package")
[1] "Biobase"
> U95B <- as(U95B,"ExpressionSet")
Error in validObject(.Object) : invalid class "ExpressionSet" object:
featureNames differ between AssayData members

Anyone got any ideas what that means and how to fix it?  Also isn't it a
bit odd that justGCRMA produces the old type of object?

Thanks
