[BioC] lumi and/or beadarray for getting beadSummary

Wed Sep 7 01:38:06 CEST 2011

I'm hoping someone can point me in the right direction.  Some months ago I analyzed some Illumina mouse data using the lumi() package since the data  received was a beadSummary data file.  As I sort of understand things, this is a summary file output by Illumina's GenomicStudio software (or maybe it is BeadStudio?).  I now have received some more Illumina mouse data (tif, xml, loc, txt, csv, idat files), but this time it is bead data.  I've used the beadarray() package to look at this data and that works just fine.  What I was wondering is whether the beadarray() package can create something similar to the beadSummary data?  I've read through the beadarray vignette but can't seem to figure out how to do this (or whether it is possible).

Thanks very much for any help,
Dick
