[BioC] R: arrayQualityMetrics error

[Manca Marco (PATH)]

Could it be related to the installation of the library libxml2 on your linux machine?

Could you give us your capabilities() and traceback() after the error message?

All the best, Marco

Oggetto: [BioC] arrayQualityMetrics error

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
