Probes, probe sets and reference sequence. Reference sequence matching all the probes from probe sets in the official mapping. The reference sequence is represented by a long dark cylinder, while the matching probes are represented by red or yellow fragments of cylinder. The wire frame represents the grouping of probes in a probe set in the official mapping. (Top:) All the probes matching the reference sequence constitute a probe set in the official mapping. (Bottom:) All the probes matching the reference sequence constitute two different probe sets in the official mapping.
