Challenges in screening of unc-43-dependent regulation on tph-1. (a) Probability histogram of tph-1 expression levels in between wild-type and single mutant (unc-43). (b) Empirical cumulative distribution functions of tph-1 expression for a different set of worms, which illustrate day-to-day variations. The n value represents number of worms imaged.
