[R] standard errors for expression intensities

Hello!

When I use the functions rma() or justrma() in the Bioconductor affy package, the standard errors for the expression estimates computed by the function se.exprs() is a matrix of NA's. I am wondering if any of you have encountered this problem and if there is a solution. Any help would be appreciated.

Thanks,
Karthik.
