Effects of probe masking on the estimated expression level. Each circle reflects the slope of the regression divided by mean squared error for a single probe set for a regression using all 48 samples: A) Effect of masking random probes for probe sets where all 14 probes are perfect matches for both D. melanogaster and D. yakuba, B) Effect of masking in probe sets where probes masked have diverged between D. melanogaster and D. yakuba (all other probes in a set are perfect matches for both species), C) Effect of masking for all probe sets included in the analysis.
