MesoRD - Mesoscopic Reaction Diffusion Simulator
MesoRD is a tool for stochastic simulation of reactions and diffusion . In particular, it is an implementation of the Next Subvolume Method [3, 4], which is an exact method to simulate the Markov process corresponding to the reaction-diffusion master equation [5, 6, 7]. Following version 0.2.0 MesoRD also supports mean-field simulations. Starting with version 1.0, MesoRD supports high spatial resolution for bi-molecular reactions .
Simulation of the Min-system in E. coli
MesoRD has been used to model the stochastic contribution to different mutant phenotypes in the Min-system in E. coli . Visualisation of a stochastic simulation of a wild type E. coli cell is shown below. MinD on the cell membrane is shown in red and MinE in complex with MinD on the membrane is shown in blue.

The development of MesoRD up to version 0.2.1 was funded by grants from the Swedish Research Council (Vetenskapsrådet) to Måns Ehrenberg, Uppsala University. The development of later versions has been funded by ERC grant "TF kinetics in vivo" and SciLifeLab-Uppsala.
