Hello, I am working with Affymetrix GeneChip Rice Genome Array, and I would like to know which probes are representing negative control in this array. I checked the information sheet, control probes are mentioned but the type of control (negative/positive) is not specified. I would like to know if there is an R function that can retreive negative control probes. Thanks.

That array is a PM/MM array, so each MM probe is meant to be the background for its corresponding PM probe.
