[BioC] affyQCReport with drosgenome2cdf

Hi Assa

are you using the updated version of 'arrayQualityMetrics'? (see:
https://stat.ethz.ch/pipermail/bioconductor/2010-November/036459.html )

What is for you the result of
           nrow(rawData) ?
(The function assumes that 'nrow' and 'ncol' applied to the data object 
provide the correct spatial coordinates)

I suspect that the spatial plot (sub)function does not work for some 
array types. However, you should get a report containing all the other 
types of report sections. And I hope the spatial plots can be fixed for 
the next release.

	Best wishes
	Wolfgang
