[BioC] Affymetrix microarray normalization based on hybridization spikes

[federico.comoglio]

Hi,

I'm performing Affymetrix GeneChip microarray analysis. I I was wondering if the normalization procedure that exploits the hybridization spike intensities is already implemented in one of the Bioconductor packages. If yes, can you kindly indicate me where?
I have tried to figure out that by myself looking at the many package guides but it seems it is no part of the current releases.

Many Thanks for your time,
