Hi Moritz,

That's not an error I've seen before.  Can you give the output of the
following command:

class(BSData.normalised)

We've made a lot of changes to beadarray recently, but as far as I know they
shouldn't affect the ExpressionSetIllumina class.  Did you generate
BSData.normalised a while ago (with an older version of beadarray) and come
back to it?

Thanks
