Figure 2. Fixed interval versus explicit simulation output.

Figure 2

Hundred stochastic simulations until t = 60.000 min (Inline graphic time steps) were done with Inline graphic min−1, Inline graphic min−1, Inline graphic min−1, and Inline graphic min−1. (A) Accuracy of mean and standard deviation estimates as function of the number of fixed intervals. (B) Simulation time with fixed-interval output increases with the number of fixed intervals. Fixed-interval simulations were done with the StochPy interface to StochKit2 and include the time to calculate the associated probability distributions. (C) The stationary mRNA distribution for Inline graphic fixed intervals (red error bars, 1.96 Inline graphic) vs. explicit output (blue 95% confidence interval). Note that 1.96 Inline graphic corresponds to a 95% confidence interval. (D) The stationary mRNA distribution for Inline graphic fixed intervals (red error bars, 1.96 Inline graphic) vs. explicit output (blue 95% confidence interval).
