Effect of the snapshot interval (SSI) on the appearance of the trajectories of state variables. Individual simulations using the same random number seed were performed with different SSIs ranging from 1 sec to 100 sec. The first row is the exact trajectory using the event log data. The other plots are obtained based on the snapshot data from simulations using the indicated SSIs. The x-axis is the time (sec) and the y-axis is the number of molecules of the given state variable. All plots were created using the 'Create Plots from Data' tool in the BNS Analysis Toolbox. Column: (A) – RNA polymerase (RNAp – s001); (B) free geneA_mRNA (s009) and geneB_mRNA (s024); and (C) Sub_1 (s233), Sub_2 (s237), Prod_A (s240), Sub_3 (s245) and Prod_B (s248).
