Hituri K, Linne M-L (2013) Comparison of Models for IP3 Receptor Kinetics Using Stochastic Simulations. PLoS ONE 8(4): e59618. doi:10.1371/journal.pone.0059618 We provide scripts for the four models compared in our study: Othmer HG, Tang Y. Oscillations and waves in a model of InsP3-controlled calcium dynamics, London: Plenum Press, volume 259 of Experimental and Theoretical Advances in Biological Pattern Formation. pp. 277-300, 1993 - Dawson A, Lea E, Irvine R. Kinetic model of the inositol trisphosphate receptor that shows both steady-state and quantal patterns of Ca2+ release from intracellular stores. Biochem J 370:621, 2003 - Fraiman D, Dawson SP (2004) A model of IP3 receptor with a luminal calcium binding site: stochastic simulations and analysis. Cell Calcium 35: 403-413, 2004 - Doi T, Kuroda S, Michikawa T, Kawato M (2005) Inositol 1,4,5-trisphosphate-dependent Ca2+ threshold dynamics detect spike timing in cerebellar Purkinje cells. J Neurosci 25: 950-961, 2005 The work described in the study was done with STEPS version 1.1.2. on a Linux computer and has not been tested on newer versions. For more information about STEPS, please visit http://steps.sourceforge.net/STEPS The scripts require that you also have NumPy installed. For more information about NumPy, please visit http://www.numpy.org/ The Figures in our publication were plotted with MATLAB. The provided MATLAB script (run_IP3R_P0.m) will run the simulations and plot the Figure 2A in the our publication. The simulations will take several hours. Simulation results are stored in ip3r_MODELNAME_op_res.dat files and used Ca2+ concetrations in ip3r_MODELNAME_op_ca_concs.dat files. Please read run_IP3R_P0.m for more information about running the simulations and plotting the results. If you do not have MATLAB available you can run the simulations from command line: - go to the folder IP3Rmodels - run each of the simulations separately (each will take time from 10 min to 2 h): python models/sim_doi.py python models/sim_fd.py python models/sim_dli.py python models/sim_ot.py - the results will be stored in .dat files and you can use a software of your choise to plot them
