Illumina Snp-Array Annotation For Probe Type (Snp, Cnv, Control, Gap Filling, ...)

Question

[Irsan]

Anyone knows how I can retrieve the probe (marker/feature) type (like "SNP-probe", "CNV-probe","gap-filling" or "control") of each probe from the Illumina OmniQuadS1 beadchip?

I have been searching at the products' support download page but I can only find probe annotation in terms of index number, chr name, genomic postion, gene name. I can guess the probe types from their names because some start with "rs" and some with "cnv" but I just want to do it the clean way. I would like to have the probe types because I want to see if there are performance differences between each type
