For a given probe set, the same probe had the largest fluorescence intensity in the majority of arrays. This figure represents the distribution of the maximum rank sum of the probes in each probe set divided by the number of probes corresponding to this probe set. If, for a given probe set, the same probe had the highest fluorescence intensity in all 7 microarrays considered here, we expected that this maximum rank sum divided by the number of probes would equal 7.
