This directory contains the scripts for computer simulation 2 (performance dependence on noise level) from Legenstein R, Pecevski D, Maass W 2008 A Learning Theory for Reward-Modulated Spike-Timing-Dependent Plasticity with Application to Biofeedback. PLoS Computational Biology 4(10): e1000180, Oct, 2008 The produced result is supplementary figure 6. To create these figures you need to: 1. The simulation performs 9 runs of the same experiment, possibly on different machines in parallel. To change the names of the machines where the experiments should run, edit the start_simulation.py file. The default values are cluster1 to cluster9. 2. Execute: start_simulation.py This is an executable file, you don't need to run 'python start_simulation.py'. The program will create a new directory where the output files will reside. Wait until the simulation finishes. You can monitor the simulations in the sim[0-8].out files in the newly created directory. 3. Then, to create supplementary figure 6 run: ipython -pylab figure_noise_levels.py
