Greetings, I am matching the PM and MM intensities from ReadAffy to the probe$sequence from the matchprobes package and not 100% sure that the order of the intensities are in the same order as probes in the metadata probe file. The list of probe ids might be possible from the probeset class but I don't know how to get the probe ids equivalent to the probe$sequence or the probe file.
