processing Illumina HT12v4.0 expression data from GEO

Hi Guys

I would like to know the basic analysis workflow for downloading and processing a Illumina HTV12 expression data from GEO. I have seen the beadArray vignette but not sure which normalization process to use.

For example with Affy datasets I normally download the raw data and normalize it with fRMA package to produce a final expression matrix of genes.

Here is some code but basically the final goal is to produce a normalized expression matrix at genelevel.

library( GEOquery )

gse <- getGEO("GSE58037")
gse <- gse[[1]]
mat <- exprs(gse)

Appreciate any pointers

PS: cross posted on bioconductor mailing list

Thanks!
