[BioC] RMA and quantile normalisation

[Arne.Muller at aventis.com]

Hi All,

somehow from the back of my mind I think that this was already discussed here
aoms time ago, but I cannot find the postings, os please excuse if this is a
duplication ... .

When processing some chips with RMA background correction, crooss chip
quantile normalisation and "pmonly" probe set summary, the distribution of
the intensities per chip is not normal.

I haven't tried
