                    Hi everyone
We just got a new HPC system to speed up our analysis, but we are
having some problems with the end part of a arrayQualityMetrics run.
It goes fine until section 5, were it is interrupted by an error
> arrayQualityMetrics(rawAffyData, outdir="quality", force=T)
The report will be written into directory 'quality'.
[[1]]
[[2]]
[[3]]
[[4]]
Error in UseMethod("xmlAttrs", node) :
  no applicable method for 'xmlAttrs' applied to an object of class
"NULL"
In addition: There were 39 warnings (use warnings() to see them)
Our sessionInfo and capabilities are below. R is compiled natively and
most of the required libraries are present and compiled with the
system. Any help is appreciated.
Cheers
Paulo
